Combining audio files

Is there a way in Automator (or some other OSX app) to combine 2 or more audio files into 1? What I imagine in Automator is to set up a list of mp3, wav, aiff or other audio files, and then have the content of one audio file added to the end of the other audio file, practically turning a whole playlist into one single file? Oughta be possible ...

perhaps this (rather old) read could provide a workaround.

AppleScript to compile audio files into a sequence

Here's the challenge: I use Skype as my office phone and everyday have to record a voicemail greeting specific to that day: "Hi this is Brian and for today, Wednesday, September 28th, I am in the office. Please leave a message and I will return your call as soon as possible. Thanks." Some mornings, I might be in a noisy environment, have a hoarse voice, or whatever, (or forget to record the greeting) and I would like to prerecord the greeting audio elements ahead of time and use an AppleScript to assemble them automatically.
I am thinking the assembly would involve two audio "constants" and three audio "variables".
[constant: greeting open] Hi this is Brian and for today
[variable: day of week] Wednesday
[variable: month] September
[variable: date] twenty-eighth
[constant: greeting close] I am in the office. Please leave a message...
I'm not really worried about special circumstances, like when I am out of the office, as I could record those individually.
Can anyone think of how this could be done in AppleScript so that it would automatically recognize the day, month, and date, pick the audio elements, then send (perhaps through Soundflower) the combined audio file to Skype for the voicemail greeting?
Thanks for your advice!

Pressing F will match the Playhead from the Canvas to the Viewer when the Canvas or Timeline is the active window and from the Viewer to the Canvas when the Viewer is the active window.
Shift F will locate the source clip in the Browser
Turning off Auto Select for the video tracks in the Timeline will match back to an independant audio track -for instance a piece of music, when you press F.

Combine audio/video files

Does anyone know of an automator action I can use to combine multiple files into a single one?

You would need to do this in a video editing program such as iMovie (though its separate handling of audio and video may be limited) or Final Cut Pro. Try asking in the iMove forum. It's not something you can do with Automator by itself.

Combine .mov files audio lost

When trying to combine .mov files from Nikon D7000 using QT Pro the audio is lost on the file that is pasted in. I have followed the instruct on page 31 of the manual that are very simple of selecting all in one file and edit-copy then open the next file and edit-paste to the beginning. When you play it back the audio from the pasted file is lost. Is the way the product actually works or is the some simple I have missed?

Does anyone know if this the expected behavior of Quicktime Pro when combining .mov files that the audio from the one being added to the other is lost?

How do you combine audio and video files?

I've brought in a video file and an audio file, but can find no way to specify that they are a single source that should be compressed together. The documentation was of no use. How do you identify video and audio files as being one source?
Thanks!

Semantics, I suppose. In any case, you do need to go through Premiere Pro if you want AME to do the job. There are likely other encoders out there which can perform the muxing, though, if you'd rather not go through PP.

Can I Re-Combine Audio & Video Files??

A post-production house took my DigiBeta and created two separate files for a DVD Studio Pro project: one VIDEO file and one AUDIO file.
I'm now trying to use those two separate files for a different project in iDVD. (I do not have DVD Studio Pro.) But, since iDVD can't use two separate files, I need to find a way to make them into one file that iDVD can use.
Any help?
(This question was also posted in the iDVD forum, but this DVDSP forum seems more appropriate for the level of technical assistance needed.)
Thanks.

What format are the files? I'm guessing that you have mpeg2 video and PCM audio... These are pretty standard formats for any tool for creating DVDs, except of course iDVD. If you have mpeg2 files, your best bet would be to get the a higher-quality quicktime, since even if you use a third party tool to re-mux the audio and video, and export it to some other quicktime format, the media will have been compressed, converted, and re-compressed by the time iDVD puts it on a disc, which not only means quality loss, but also high potential for "glitchy" playback.
I never use iDVD, because I have DVDSP. But I checked the manual and it says it definitely does not support mpeg2, which seems very strange to me. There may be enother tool you can use such a toast to make the DVD, but your best bet is to either use DVDSP with the files you have, or get new quicktime files (which might be hard) to use in iDVD.

Combining Multiple Audio Files

Ok. So if i have about a hundred 3 or 4 minute audio files that i want to put together into one large file that will be like hours and hours long... like an audio book. Can I do this in garageband or imovie? Or do i need another program.

My first thought would be to just drop them all into iTunes and create a playlist with just those files.
As an alt, I would suggest an Audio Editor

If really you want to use GB, you need to be aware of its default limits

Combining and matching the sound of 2 audio files

I have an audio file, speech only, that was recorded in 3 different sessions. the 3 segments don't match in tone. Is there a tool that will sample all 3 pieces and smooth the whole file out, so it sounds the same? If not, where can I go to find out how to manually adjust the pieces of the file?

I think I'm going to have to make an FAQ about this, as it comes up quite often.
Sorry to be the bearer of bad news, but basically, you can't do it. At all. Whatever you do.
The human voice is something that we are all very finely attuned to, and we are used to detecting every minute variation there is in it. This is why we don't let VO artistes anywhere near the pub at lunchtime, and generally only let them drink clear liquids. Even if a voice moves across a room, it tends to sound different. You even have to be careful with comfort breaks, and make sure that the reading position is the same afterwards. Change the day, and have your reader catch even the start of a cold - and they'll sound different again. And I could go on - there are plenty more things that can change a voice too. Just the mood the reader is in can do it!
A lot of people spend absolutely ages trying to rectify these problems, and just end up doing what I do in the first place now - re-record. Ideally get the whole thing in one session without any breaks, if you can - that minimises the issues.

Where can I READ how to combine an audio file with a slide show

I need to make a dias show running with some speech/audio file beneath - so that I get an avi file or whatever to present on the internet.
But no matter where I turn, I find video after video - and I am not so stupid, that I cannot read a text.
So can someone tell me where I can find a TEXT manual, describing how I do that?
Thanks a lot.
Niels

Hi,
Are you in Premiere Elements Editor? I'm seeing in PSE Organizer and can't see that "Drop files here" text anywhere.
This is how Slideshow dialog looks in PSE11 Organizer. You can rearrange the images by clicking on "Quick reorder"button or by dragging thumbnails on the thumbnail strip you see at the bottom.
Let me know if you are facing any issues with this dialog
Thanks

How can I convert the download.m4a and Info.plist into the right audio file

The topic is actually the problem that I have.
I have bought music and it was downloaded successful (all of it) but iTunes had a strange freeze while converting the files into the right audio file. Some files were converted but after the freeze no more.
I'm now left with these .tmp folders in the downloads folder which have the download.m4a and Info.plist files.
My iTunes is able to play these download.m4a files, but they show no information and covers and this is really annoying. I could write and change it all by myself, but than I would still miss some information (and covers).
Is there any way for me to convert or combine these files?
Note: I'm not able to restart any downloads, because they were successful.

Hello ed2345,
Thanks for the help, but this is not the problem.
It's hard to describe the problem, but I'll try it again, this time with pictures.
I was left with the following folders in the iTunes Downloads folder.
http://www.picfront.org/d/7yb3
These TMP Folders have a download.m4a and a Info.plist file.
After moving the audio files in iTunes a bit I get this.
http://www.picfront.org/d/7yb2
As you can see no other Information for the download.m4a than the length.
That's how the .m4p file looks like
http://www.picfront.org/d/7yb1
And this is how the same .m4a file currently looks
http://www.picfront.org/d/7yb0
Like I said, I could edit all these download.m4a files by myself but that would leave some information out.
Note: Sorry, I hope the links do not spam you with annoying ads. I don't get any but I was told that there can be some annoying one.

Export all tracks as audio files in LPX has suddenly ceased to function correctly

I have been working on a project for the past three months, which requires me to work from home ,then export all my tracks as audio files and take them into another studio. This is because my collaborator's DAW of choice is now Nuendo. So far, this has proved to be a very successful approach to our workflow, until today. As an example , I have a cue with 96 tracks. When I came to use export all tracks as audio files, the usual window came up, defaulting the destination to the bounces folder in the Logic song. However, this time, instead of the expected and correct number of tracks to be saved ( 96 ) , the total was 25 !
I tried this with a few other recent Logic songs and the same thing happened. None of us can figure it out. I had to manually, and individually, bounce each track separately, which was very time-consuming. A clue, though….. I tried exporting the tracks one at a time. So, the first one was, say, piccolo rips. It did that fine . The second track was Alto flute runs, but when I came to export, Logic seemed to think it was still the piccolo rips! This implies that the reason why I'm experiencing reduced export files is because Logic is thinking that many of the tracks are actually duplicates, so it's stopping them from being exported. That's the only explanation I have. However, I don't have the answer to the reason for this. I'm running the latest version of Logic.
Has anyone clue as to why this has suddenly started to happen and how it can be fixed please? I'm thinking I might just trash the Logic app and reinstall.
Many thanks for any help.

First of all you are welcome...
I have to say... I suspect something has changed even if you are not directly aware of it.... between the time it did work and now that it doesn't for you... Be it for example... an update to a plugin you are using.. or even a new/different plugin you are using now that you didn't use before...
I checked with one of my clients a few minutes ago, who does regular, several times a week, large project stem exports to see if he has ever had or heard of such an issue ( in case it one of those odd bugs that only rears its head every now and again..) and the answer was no, not at all...
So all I can recommend is to create some testbed projects.. using different combinations of Plugins, creation of tracks methods.. templates etc.. until you uncover the root cause of the issue... because i suspect it may well be something unique to your system, config or work method that is causing this problem..
You might also want to check with the guys at
http://www.logicprohelp.com/forum/index.php
..and see if David, Jordi, Eric or one of the other regulars there, have ever come across such a problem.. I did a quick cursory search there and found nothing at all but it was a very quick look/see type of search...
Maybe CCT, Pancenter... or Edgar here.. might have an idea or two, too...
Finally, Can you also state your current OS X / Logic version please...
Cheers..

Audio files not embedding with .avi files in CS4

I am working on a project in Premiere Pro CS4. I successfully captured with firewire a number of clips and the audio embedded with the clip ( one .avi file shows up in explorer under the project. When I went back into the project, first, there was no audio captured at all and I did'nt notice until I had captured half of the clips (45 minutes). I don't know what happened there. Now, the audio is attached to the .avi file, but is not embedded like the previous captured files. Example First capture: File Name : Harlem 01.avi audio is embedded 2nd Capture Guilford 01.avi and Guilford 01. Stereo 1.wav
Why aren't the .avi files and the audio files embedded and combined as one file anymore?
Thanks for any help.

>Matrox card
The comment I have often seen is to the effect that "a Matrox card makes a good door stop"
For a Firewire transfer you don't need any "card" at all, only a Firewire port... usually on the motherboard
That said... and you mentioning switching back and forth between different Matrox modes... I would guess that, yes, you selected a wrong option
But, since I don't use Matrox, I have no idea what setting could be wrong (I do use a Pinnacle Dv500 via dual boot with WinXP to digitize some old VHS tapes before they stop playing... but once I had settings that worked to create AVI files that ARE Audio Video Interleave with everything in one file, I have never changed any of the Dv500 settings)

Hi:
How can I edit MPEG or convert DVD or MPEG to DV
http://www.sjoki.uta.fi/%7Eshmhav/SVCDon_a_Macintosh.html#edit_convertMPEG
Matti says it better than any of us:
how/where you can join clips with Streamclip
Also MPEG Streamclip guide explains it.
MPEG Streamclip can join similar MPEG files: The joined files must have the same PIDs, the same start codes, and the same audio/video properties (that is, they must come from the same source or channel).
Using "Convert to MPEG" before joining the files can be helpful, because it changes PIDs and start codes to a default value. The preferred method to join streams is to Copy one stream in MPEG Streamclip, open another stream and Paste it there. This method checks that the joined streams indeed are compatible. Another method is to put the MPEGs in the same folder, and rename them so that they sort as desired in list view. Then select them via MPEG Streamclip's "File/Open Files..." dialog box (Shift- or Command-click to select multiple MPEGs). Then choose "Edit/Fix Timecode Breaks". After this MPEG Streamclip should report the combined length of all MPEGs (check the Log Window if you want to know whether any timecode breaks were found). Then choose "File/Convert to MPEG... or /Save As..." to save them in a single file. If the video transition between two files looks bad, you can use the Cut command to improve it. You can join very different and incompatible MPEGs with this latter method so the end result is not guaranteed to work.
MPEG Streamclip can also edit MPEG files. Just set In/Out points (with I/O keys), Cut unwanted material off and choose "File/Convert to MPEG...". You can also Cut/Copy selections to other parts of the same stream or open another compatible stream and Paste it there. Shift-dragging the playhead can also be used to define a selection. Option + arrow keys jump to the beginning/end or In/Out points. You can use the Trim-command to more closely see a part of the video before cutting, then choose Revert Trimming to see all material. JKL-keys can be used to enable fast forward or reverse playing. The scroll wheel works also; with the Option key it scrolls 1 second per click. See the manual for more details on how to jump in single frame, GOP, 1 second, 10 second or 1 minute chunks when searching a specific spot in the video.
Editing and trimming can be accurate only if In and Out are both on keyframes because MPEG Streamclip edits to the GOP, not to the frame. For DVD and (XS)VCD the maximum GOP size is PAL 15 and NTSC 18 frames, so the editing accuracy can be up to about 0.6 seconds. You can advance to the previous or next keyframe (i.e. I-frame, the beginning of each GOP or Group Of Pictures) with the Up/Down arrow keys -- you can also use the Edit/Go to Keyframe command to see where the In and Out points really are when editing (the In point is included in the selection, the Out point is not included). Shift + Up/Down arrow keys allow fine-tuning the selection to the GOP.

The duration of an audio file

I need to determine the length of my audio file. Right now I am using .caf files, but I can see how I might this to work with mp3s also.
Anyhow, I see this tidbit from the Apple Core Audio Spec:
mSampleRate
The number of sample frames per second of the data. You can combine this value with the frames per packet to determine the amount of time represented by a packet. This value must be nonzero.
That's looking good, except this will only tell me the duration of the packet. I can't find out how many packets my total audio file has. (And yes, this is a file, not a stream.)
What am I missing? Any help is appreciated.
Thank you.

Unless I am mis-interpreting the question this should work:
+(NSTimeInterval)getDurationForAudioFile:(NSString*)path
OSStatus status = 0;
AudioFileID audioFile;
NSTimeInterval seconds;
UInt32 propertySize;
propertySize = sizeof(seconds);
status = AudioFileOpenURL((CFURLRef)[NSURL fileURLWithPath:path],
fsRdPerm, AUDIOFILETYPE, &audioFile);
status = AudioFileGetProperty (
audioFile,
kAudioFilePropertyEstimatedDuration,
&propertySize,
&seconds);
return seconds;
