Vocoder (EVOC 20) question: Must audio track be prerecorded?

I've been playing with the EVOC 20 vocoder, and it works great with a prerecorded audio track. But I want to be able to speak the words and play the keyboard simultaneously -- is this possible? I tried setting the side chain to be a new audio track and talking into it while playing, but no sound comes out of the vocoder. Can this be done? TIA... Mark

Hi Eric, and thanks for the suggestions.
It turns out that what I needed to do was record the audio and software tracks with the side chain of the software track set, not to the audio track, but to the same input as the audio track. This lets me sing and play and hear the "vocoderized" vocal live.
Then, for playback, I set the side chain of the software track to the newly recorded audio track and all is well. Latency didn't seem to be a problem, either, so I'm all set!
Thanks again,
Mark

  • Beginner question: Two audio tracks become one - how to undo?

    I know this surely is a beginners' problem, i hope for a quick reply anyway. I've imported material I had before logged with AVID Liquid, into Premiere CS4. In order to get video and audio together I had to put video and audio in a new sequence by hand. I then loaded this seqeunce into the source monitor to be able to cut my material (one video track, two audio tracks (one from a directional mic, which I don't always want))  from there. But when I paste a clip in my editing sequence I only get video plus ONE audio track in the stereo track. But I need both audio tracks because sometimes I'm going to delete one of them. So my question: How do I get video and BOTH audio tracks from one sequence to the other?
    Thank you very much, you've had much patience with me with similiar questions.
    Niklas

    To do what you want, you won't be able to work with the media as a single clip.  You'd have to go into the sequence with the video and two audio tracks, and pick out what you want from there instead of the Source monitor.  Make your cuts, laso the clips you're using, then do a Cut/Paste from the main sequence into the edit sequence.  Make sense?

  • Two questions about Audio Tracks

    I need to make several adjustments to an audio track of an interview to remove the voice of the interviewer who would give the occasional "uh-huh" etc., sometimes overlapping (though usually not) with the interviewee.
    The way I've been doing this is to pull down the db level at those points in the timeline.
    My questions:
    1. Is this the best way to do it?
    2. Regardless of the answer to question 1, why is it that sometimes when I use the pen tool in one stereo track, it will automatically affect the other at the same time, and other times I need to do each stereo track separately?
    Thanks a lot.

    If you recorded with two mikes, which it sounds like you did, you really recorded two distinct tracks, and you ought to bring them in as dual mono tracks, rather than stereo. (A capture setting.) Go to the Modify pulldown and uncheck "stereo pair." Then you should be able to adjust to your heart's content.
    Did you record any room tone? It's very useful to fill in the gaps you create by eliminating words. Nothing detracts from an otherwise compelling show like bad audio! If you don't have any room tone, look for a section where no one is saying anything and there is no clothing rustle, etc, FROM THE TRACK where you are making deletions. Use that to fill the holes.

  • Question about multiple audio tracks

    Hello,
    I see that imovie has only 2 audio tracks available when creating a movie. I need more than two since I will be working with a voiceover track, a soundtrack and at least one background/environment track all at one time. I won't be able to use the sound recorded with the video so that "track" is not an option.
    My question is; Am I out of luck here and need to spend the 1K for studio pro to add more multiple audio tracks?
    Also, I tried working with garageband but since all of my audio tracks import in at a minimum of 40 beats per minute, the voiceovers are all sped up and sound chipmunky.
    Thanks for any help!

    Well I didn't mean to irritate you...LOL And yes, I realize that this is the iM 6 forum but the gist of my question was related to multiple audio tracks in iM and thought I would ask about it in the forum pertaining to the latest release.
    I had already posted a question in the GB forum regarding the bpm problem and found no answers so I was pretty much about to shelve that idea and forgo the whole garageband thing; this without knowing about the new "swap" features. I just updated to iM 6 yesterday.
    As far as the "on-tape" raw audios: I was working on my movie in iM4. I wanted to add more audio bits but I don't have a proper mic for my G5 so I recorded the audio bits on dv8 tape through my camcorder. I imported the video (the image was the inside of my lens cap!), extracted the audio, took those audio files and imported them into GarageBand. That's when I noticed the bpm problem.
    I'm sorry about the lack of info I originally gave but like I said, I had pretty much gave up on the idea of using GarageBand. I'm pretty new at this and I'm trying to decide what I need in terms of software to get what I want out of my movie. I'd be willing to pay for FCxp but still looking into whether I need to do just that or whether I can get by by using imovie and now it looks like GarageBand too.
    ah, thanks for that
    what irritates me, Prince wrote:

    iM 6 allows now "swapping" files with GB3... (I'm way

    so, video is in some iM, and he wants to use the

  • Questions on sending audio tracks from a short film into Audition for mastering

    Ok so basically I have a 4 minute film in which i need to master the audio. I have a few quesions as to how to best go about this.
    1: Some of the clips came with 2 tracks off the camera yet they are both labeled channel 1 on the beginning of the clip on the timeline. Their properties are listed as follows:
    Type: Windows WAVE audio file
    File Size: 16.0 MB
    Source Audio Format: 48000 Hz - 24 bit - Stereo
    Project Audio Format: 48000 Hz - 32 bit floating point - Stereo
    Total Duration: 00:00:58:09344
    Why are there 2 tracks?
    2: Some other audio tracks are just labeled on the timeline as L and R. Both these and the other ones labeled Ch 1 are synced with Pluraleyes from an H4N Zoom recorder so i have no clue why they are labeled different. These one have properties labeled as such:
    Type: MPEG Movie
    File Size: 69.5 MB
    Image Size: 1920 x 1080
    Frame Rate: 23.976
    Source Audio Format: 48000 Hz - 16 bit - Stereo
    Project Audio Format: 48000 Hz - 32 bit floating point - Stereo
    Total Duration: 00:00:14:20
    Pixel Aspect Ratio: 1.0 (1.0)
    Yes those are audio files on the timeline.
    3: What is the general scoops with these multi track audio files? Do I need both tracks?
    4: What would be the best workflow to export all the audio clips into Audition and get them back in the timeline? I heard about importing then in Premiere clicking Undo so you don't have the audio track clips as "Audio Extracted" and you retain the originals, but then just replace them with the Audition audio.
    Working with sound is not yet a strong point of mine, i am just a video editor but need to get a grasp on properly handling this.

    Cameras although they can record stereo audio often only use a small mono gun mic mounted on the camera. The audio menus on the camera give you the option to record either the mono mic to both tracks (ie. Ch1 input to the camrea is fed to both) or as stereo tracks from a stereo mic or as split tracks with onboard mic via Ch1 to track 1 and, say, a radio mic fed via Ch2 to track 2.
    Your first files sound as if they came from the first of those options from an onboard mono mic. You don't necessarily need both trakc as they are identical mono tracks in this case.
    The second set of tracks were recorded as a stereo pair on the Zoom, hence L and R. They could be stereo or more likely again are double mono tracks where you will only need one of them.
    However, depending on the project, it may be more convenient to keep both tracks if any stereo music or effects are going to be mixed in on the multitrack. The final edited video will probably have two tracks on it anyway even if all the audio content is mono.

  • Questions on normalizing thousands of audio tracks.

    So I have a lot of audio tracks in my iTunes library. AAC, MP3, etc., Ripped from Vinyl, CD, mic. About 5,000 tracks.
    I am considering normalizing them through Soundbooth CS4. But, has anyone tried to process so many tracks? And what of the quality? Will it degrade the sound?
    I have the latest MACPRO Quad Core and I also have Soundbooth CS4 on a PC Pentium Dual Core. So I am considering splitting the chore to these two machines. Is this a bad idea?
    Any advice would be appreciated.
    Victor

    I would suggest using a different application to normalize 5000 audio files.  Soundbooth has a very good normalization algorithm, but is not at all ideal for batch processing that many files.
    For the most part, normalizing and resaving already-compressed audio files is going to cause a bit of quality loss as you recompress the files when saving them.  There are a few applications around that claim to offer lossless normalization, and while I'm not necessarily convinced of that claim, the few times I've tried them out there was not a noticable loss of quality.
    Check out http://www.downloadsquad.com/2007/01/04/how-to-normalize-your-mp3-volume-levels-the-right- way/  for some tips and links for Windows.  I'm not aware of any similar tools for Mac, but would advise against letting iTunes do it.

  • Audio track questions

    Hello, I filmed a few interviews with two microphones for each interview (one mic for each xlr) I did not have the mics setup correctly, so one mic wrote to one track while the other mic wrote to the other audio track. How do I copy a single audio track (ex. a2A2) and paste it again in A4 so that i can have that track play on both speaker sides?

    Set the pan state on the two tracks to center. Select them in the timeline and press Control-period.

  • Cutting two audio tracks in synchrony with video, question

    I had to chop my movie in two because it did not fit on one DVD. This forum suggested that you make a complete second copy and delete the second half of one, and the first half of the other copy and burn your DVD with the respective halves. No problem with the first half, I deleted the video and had to go back and individually delete the audio tracks and everything stayed in synchrony. The problem arises when trying to delete the first half of the movie and not being able to use the play head to delete audio and video simultaneously. The audio of the first half of the movie is preserved, and if I delete the audio one track at a time it will shift the audio in relation to the video. I thought there would be a way of chopping off the video and audio tracks at the same point without the tedious task of trying to put everything back in sync "by hand". I have two audio tracks so it might be tricky to cut at the end of one audio track, without getting the other out of sync. Thanks for suggestions.
    Mike

    Hi Mike:
    Perhaps the easiest way is to export the entire movie back to DV tape and then re-importing to imovie. That way, the entire movie is now combined into a "flattened" version. Meaning the audio and video are combined together into one video track, making it possible to split the final version in two.
    Pain in the neck, but much easier that doing it one clip at a time.

  • Newbie Question - Creating DVD from Premiere to Encore with 2 audio tracks

    Hello and thanks for your time,
    I'm pretty new to all this but seem to be getting the hang of things pretty well but one problem I'm having I can't seem to find an answer to.
    In Premiere I am creating a dvd of a football game, i have the video with an audio track of the crowd and another audio track of the commentary.  These are all edited together fine and work well.  I then use the dynamic link to send the sequence to Encore and that's where the problem occurs.
    I can't seem to get both audio tracks to appear in Encore?  Any suggetions or tips on where I might find an answer?
    cheers for the help and time
    Ian

    Ian,
    This is not a cure to the issue, but is a workaround. It's the "old-fashioned" way that things were done before DL.
    Export your Sequence as elemental streams, i.e. video-only and audio-only. Import your video-only file into Encore as a Timeline, and teh audio-only file as an Asset. From Project Panel, drag the audio to the appropriate timeline. Done.
    Now, exactly what you choose for your Export and even how you do this will depend on your Project in PrPro and also your source Assets. For SD material, I'd choose DV-AVI Type II video-only (no multiplexing), and for the Audio 48KHz 16-bit PCM/WAV. If you have a version of PrPro prior to CS4, just Export Movie (settings above) for the Video and Export>Movie (or AME) for the Audio (settings above). Just make sure that the Export Video is checked for the DV-AVI, but the Export Audio is not. Change these two checkboxes for the Audio.
    Now, for DL not working, as it should, what is the format of your source Audio? Do you have any Channel-mapping used? Does your Audio Mixer Panel show everything right there? Do you have one Audio Track either Muted, or Bypassed. Look in Audio Mixer, to make sure you do not have one Track Solo'ed.
    Also, what version are you using, CS3, or CS4? Note: for CS4, you will use AME for the Exporting in the first part of the post.
    Good luck,
    Hunt

  • Multiple use of the same video time line for different audio tracks

    I have a 90 minute video timeline
    I will be putting different audio tracks in multiple languages.
    But as i was just editing i wondered if i could use only a segment (30 minutes ) of the timeline
    along with a 30 minute audio.
    Example:
    So the first thing on the menu will be the whole 90 minute video
    with a 90 minute music track
    Second thing might be the 90 minute video with a 90 minute commentary
    Third thing might be the first 30 minutes of video with a different commentary
    Forth thing on the menu might be the first 30 minutes of video and 30 minutes of
    a different language
    Etc.
    I realize i will need to make space (mb)  for all the audio.....but if i could use the same video or pieces of it
    that would be fantastic.
    If i can do this i am presuming i should use playlists and chapter playlists to get it done?
    I have never done this before and would love some feedback on an over view or tips
    that might save me some guess work
    Thanks for any help :-)

    Hey Stan!
    Thanks for your help...i think i am really getting this. And have learned a lot.
    I had to go back to my computer programming and flowcharting skills to figure out the flow :-)
    And i still have 153mb to spare when i build it.
    I ended up lining up all the different videos and audios exactly for each time line except for 1 timeline.
    Question: I know if the audio is shorter it will be ok.... but if the audio is longer than the video on a timeline ( and its the audio i assigned it by specify link )
    Will the DVD keep playing until the audio is done or end when the video is done playing?
    2nd Question: I am previewing the playlists with the "Preview from Here" feature
    I specify the link and chapter within that timeline ( it is the only timeline with more than one chaper....the one with the longer audio than video from the question above )
    For most of the audios i only need video chapter 1.....the preview here plays it ok but if i hit the skip to next (in the preview button on theright of the play button)...it goes to the next chapter #2... instead of the next timeline chapter 1 like it is programed to do from the playlist.
    I am wondering if this is just fluke in the preview feature...or will it do that on the actual DVD as well?
    Lastly because i am using different timelines. I am wondering if there are delays between playlists? for example...i have a long audio that continues between three timelines...i have spliced it pretty fine so it picks up perfectly on the next timeline...but i am wondering if the DVD when playing in realtime will have a little black space inbetween timelines.
    Thanks again for your help and time :-)
    Mark
    Hiya Mark.
    DVD-Video is video dominant, with the audio always following the visuals so if the audio ends berfore the video it will not (okay, should not) be a problem.
    However, the other way around could go either way - if the actual video timeline has ended the audio may well truncate so I would personally add videoblack at the very least.
    I am also not at all sure how you are going to work a single contiguous audio file across 3 separate playlists. This sounds flawed in concept to me (have I misunderstood your meaning?). In DVD-Video the format is graphically/visually dominant - the audio must always be tied to a visual asset be it a menu or a timeline - so there is no way to have one piece of audio playing across 3 timelines and having it play back glitch free whilst the timeline changes. You will not get a black space - it will simply stop. So unless I have misunderstood you in some way.........
    As Stan says, preview is flaky - the only way to know for sure is to multiplex & burn.

  • Audio track restarts in the middle of a clip

    Hi!
    I'm having an interesting issue with the audio tracks in my Timeline.
    When I start playing a clip the audio is in sync with the video. Then about 5 seconds into playing the clip the audio starts over. The playhead does not go back to the beginning, but the same audio is looped over again--and of course is now out of sync with the video track. The clips are not out of sync in the Timeline.
    For example, one clip is an interview: "This duck is un-banded so I'm going to get to put a band on this duck. It's a male mallard. I can tell because it's starting to get it's green head. Although at this time of the year..." (audio cuts off and restarts): "This duck is unbanded so I'm going to get to put a band on this duck. It's a male mallard. I can tell because it's starting to get it's green head. Although at this time of the year they are molting so they don't have the brilliant green head that we're all used to seeing."
    The waveform of the audio restarting is represented when I open the clip from the Timeline into the Viewer! However if I go back to the Browser to the original clip and play that, the audio track is fine.
    What's going on here? What can I do to fix this besides grabbing the original clips from the Browser and replacing them in the timeline? Or forcing the audio tracks out of sync to match? (eek!)
    I must have done something weird...

    One example of an affected clip:
    Source is from a Panasonic HD camera--so transferred to FC from a P2 card
    Item properties:
    817.5 MB
    960x720
    DVCPRO HD 720p60, Interger (little Endian), Timecode
    Hey--could this be caused by the frame rate of the sequence? I just noticed that the sequence these affected clips are in is 60fps, and my video clips are 23.98fps. So--I copied and pasted my clips into a new 23.98 sequence and the issue has gone away. Huh. Oops... Not enough coffee this morning.
    Thanks for trying to help out--sorry to have answered my own question (duh).

  • [Help !]Exporting more than 2 audio tracks impossible ?

    Hi all,
    I am trying to export a sequence with 6 audio tracks using *Menu->File->Export->Using Quicktime conversion...* and it seems to be impossible to export to more than 2 audio tracks !
    If I use the option Export->Quicktime movie I can export my 6 audio tracks but I don't want to export to .mov file...
    Can anyone confirm or has a solution ?
    Thanks in advance.
    Tom Douce

    Nope, Red is correct on this Tom, unless I'm misunderstanding your question. Regardless of your audio hardware, to export more than 2 channels of audio you must define those extra channels by creating additional "audio outputs" for your sequence ... basically the number of audio channels in your export is equal to the number of audio outputs in your sequence settings; additionally you must map the audio tracks in your sequence to those audio outputs ... you do that by right clicking on or around the audio track lock icon / auto select icon for each channel and using the context menu to assign the track to a given output (you can also do this in the Audio Mixer toolbench window). This is the workflow regardless of whether you are exporting to a file or exporting to tape or otherwise.
    For what its worth tho, in my own quick hardly conclusive tests earlier on, exporting a correctly configured multichannel sequence "Using Quicktime Conversion" always resulted in a stereo downmix being passed to the chosen export component, so I still think you're likely to end up needing to use the private export component API to get around this.
    Hope I'm wrong tho, as it would surely make life a lot easier for you

  • Separate Audio Tracks

    I'm using logic with little knowledge of the program.
    I have 1 audio track with samples, then i needed more audio tracks for more samples and vocals, however it seems that every individual audio track plays all the other audio tracks thru it at the same time.
    I soloed the vocals to work on them but the samples are playing thru that track too? Why does one audio track play all audio tracks?

    But what does universal track mode do exactly?
    No one really knows. But it must be enabled
    Well, of course someone knows. It switches the mixer's behaviour in handling stereo tracks. UTM only uses interleaved stereo files, while split stereo files are better treated without UTM. You can google it to follow some of the ongoing discussions.
    However, the disabling of UTM can cause some problems, like you just experienced.
    Also, if you don't mind another question, when should i use stereo tracks and when should i use mono tracks?
    You should use stereo tracks for instruments (real or software) that produce a stereo sound.
    You should use mono tracks for monophonic instruments like single voices. However you can switch a mono track to stereo by using the gain plugin (mono->stereo) and/or processing the voice through a stereo effect like the stereo delay.
    Panning of stereo and mono tracks is different, also. While you can pan a mono track, you cannot pan a stereo track. What panning does with a stereo track is to move the balance between left and right channel. This you should be aware of when mixing. UTM (or disabling it) is used to solve this problem, too.

  • Audio track 1 and 2 not lined up??? help!!

    When you put clip in timeline they go on 2 audio tracks for some reason. well, i must have deleted something I shouldn't have because 1/4 way through movie the 2 audio tracks are not directly lined up with one another. for some reason the bottom track says +15. I tried to undo but you are openly allowed 10-15 or so 'undo's" and I must have made error long time ago and not noticed. Then I tried to lock the audio track 1 for my video clip and move the audio track 2 directly underneath it but it won't let me. Even when audio track 2 is unlocked I cannot move audio track 1 for same movie clip.
    When I play my movie the dialogue is not synced anymore. Can I fix this?
    suggestions?

    Birmy wrote:
    I have been told by a friend to re-do my entire movie from the point the audio track 1 and audio track 2 have become displaced. If anyone in the Apple community can help me I would appreciate it.
    I find it hard to believe that when audio track 1 and audio track 2 become displaced there is not an easy way to line them up again. Since 80% of my movie has an audio track 2 clip that has a red icon with + 15 on it it seems to suggest that audio track 2 is 15 frames off of audio track 1. (Audio track 1 and Audio track 2 are from the same video clip)
    So I have about 20% of my movie clips that have lined up Audio track 1 and Audio track 2 and then all of a sudden the audio track 1 and audio track 2 are not lined up. So I hear an echo to every actor who states dialogue because audio track 1 "says the line" and then of course audio track 2 which is not lined up "says the line" a few seconds later.
    If anyone can answer this question you will save me about 10-15 hours of work. Thank you!
    Your friend is, umm, to be kind, ignorant.
    There is an easy way. Right click on the red icon and select slip into sync.
    The most likely explanation is that you have deactivated the link function of the timeline. It is a small chain link icon in the right upper corner of the timeline button bar.
    Since you are having so many problems associated with yoru project's audio, I strongly urge you to learn how to increment your project on a daily basis so you have an intact version history (no, I'm not going to explain that to you) and be absoltuey CERTAIN you understand how the auotsave vault works and how to recover your project if you need to.

  • Can't record software instrument track to an audio track

    I'm frustrated at the moment. I'm sure this has worked before.
    I have a project that contains external MIDI tracks, software instrument tracks and Garageband instrument tracks. All tracks play when I unmute them. The external ones play thru a Roland synth and audio comes back via ADAT thru my Firestudio interface.
    I created an audio track for each MIDI track. I can record the output of each synth track as audio one at a time. But if I unmute one software instrument track, send it's output to channel 1 and 2, set the inputs of my record-enabled track to 1 and two I get no audio recorded. I know it's gotta be something simple that's wrong, but can't figger it out.

    If you want to record an internal software instrument to audio you can just select the track and use the "export track as audio" command from the file menu. Or you can select the regions and use the bounce in place feature or solo the instrument in question and use the bounce command and import the resulting file. Logics INPUTs 1 and 2 are not the same as Logic's OUTPUTS 1 and 2. If they were you'd get a feedback loop. If you are careful and MUST do it this way, you can cable from outs 1&2 to inputs 1&2 but you must first disable the output the track you are recording on to to avoid feedback.

Maybe you are looking for
