Track audio using AIFF

Hi, I have a client who claims to be using the aiff files of his compressed mpeg2 files(from compressor) in DVD Studio Pro for track audio. The key is that he says that he never compresses the aiff files to AC3 format. I can't seem to figure out how this is possible. Is it maybe that DVDSP is automatically converting the aiff down to ac3 when he builds the DVD? It just wouldn't fit otherwise. Also, I would imagine the bitrate for running a mpeg2 at around 6mbps along with the aiff would be too much for the DVD spec.
Any ideas?

No, DVDSP won't allow you to continue on. You will see from time to time posts here that run into that problem. They generally go something like this: "DVDSP stops in the middle of building with an error saying the bitrate is too high, what's up with that?" (forgive me for taking some liberty in the quote). What's happening is the user has aiff or wav for their audio, and somewhere in the video stream the two combined bitrates exceed the max allowed. It can be very frustrating, because it can happen anywhere in the stream, and you really have no idea where it's at. VBR encodes with DVDSP/compressor are the most notorious for putting bitrate spikes in the encode. CBR is better, but not immune. The solution is to either re-encode the video at a lower bitrate (not desirable, and takes a longer time and may or may not be low enough); or to compress the audio to ac3 (which generally gives enough 'head room' to get under the max allowed even if there are spikes).
The short answer to your question is that DVDSP won't allow you to make a non-compliant disc (based on bitrate allowances). It also is not very helpful in letting you know exactly where the problem is.

Can you export multi track audio using FCPX?

hey guys
i can only find export audio under the "share" menu
and it has aiff,aac and mp3, no wav or omf and no options to include as multi tracks rather than a single stereo track or 5.1 surround
do you guys know of a way to export multiple tracks? without muting every track and export numerous times of course

Typed this hours ago and forgot to post it.....
Have actually done that and sent a test piece to the broadcaster. Not sure if I have got the audio tracks in the right order.... from top to bottom would that be audio tracks 1-4, with four at the bottom? I am waiting to hear back from the broadcaster to see if the test piece works as they expect it to.

I've imported a giant cd collection for my boss in wav format for the best quality audio using iTunes version 11.1.1. I need to transfer this library to our Music workstation using iTunes 11.0.1. That workstation version of iTunes can't be upgraded for compatability reasons with other software using iTunes. When I try to transfer the library I lose all of the CD metadata and end up with only track names. Is there a way to transfer everything along with the metadata?

Not easily. WAV format does not store tag information in the file. Realize both AIFF (equivalent to WAV) and Apple Lossless (full quality but smaller files) do, so WAV was unfortunately the worst format to chose.
If you have to go with what you have you will have to explore exporting the library as .xml, moving it and the files to the other computer, then rebuilding a lower version library with the two sets. I am not sure if you can do it with the library.xml file that already exists or if it too differs according to version. You may end up having to export the files as a playlist. You will, of course, lose artwork too, though you can try fetching it from the iTunes Store later.
Some of what you need to do is outlined in these articles though you have the added limitation that you are not building a library of the same version. (It really is a piity you choose WAV, otherwise you could have simply added the ripped files and most of the data would have traveled with them.)

Audio to aiff

Hello.
I am having a problem when exporting audio to aiff. If I export one track with aiff, and import it again to the same project and the same sequence, the aiff file is longer than the video and it de-sincronizes progressively. If anyone knows where the problem is, please let me know.
thanks...

Take care your AIFF export settings match your timeline audio settings: i.e. 48 kHz/16bits.
Differences in the kHz uses to cause such kind of unsinc issues.
Hope it helps !

Using compressor DVD Studio Pro 4 will only accept ac3 format in the burn process. ac3 makes a nnsense of the good sound delivered, 30% reduction in volume, auto volume levelling giving unwanted volume variations. Used to be able to burn using AIFF/WAVE,

AS Above. Edited in FCPX. Excellent sound file. Using Compressor 4 to DVD Studio 4. Wanting AIFF or WAVE sound for acurate sound.
Previously DVD Studio 4 has accepted AIFF etc and delivered sound as reuired. Now, during the burn process everything other than ac3 is declined as 'video bit rate too high', but will burn if the AIFF format is replaced with ac3 (which I presume meanss the 'video bit rate too high' is referring to the sound file)
The issue with ac3 format is the huge reduction in original volume and worse, the 'auto volume levelling' that makes a nonsense of the original soundtrack - with simply aweful unwanted variations in volume Throughout the the dvd.
I have tried everything I can think of to get around this. The 'volume gain' in compressor doesn't make any difference. Exporting just AIFF and the Video to DVD 4 doesn't make any difference, it always declines anything but the aweful sound ac3 delivers.
I have customers awaiting a musci DVD, not with thei quality I can't.
Cheers

The total video bit rate is determined by audio & video. Depending on what rate your video file was encoded at will determine how much room is left for audio. PCM(aiff/wav) audio requires a bigger piece of the pie. Video bit rate too high means your overall(video+audio) rate is going above 9Mbps which the format won't allow. The only way to use aiff would be to lower your video file's data rate. The length of your program is also a factor in all of this.
I had some problems in the past with using aiff instead ac3. Although there shouldn't be any issue I experienced playback issues on some players that couldn't be explained but were cleared up by ac3. I have been using the same specs as Dave's suggestion for almost nine years and have not had any issues with mix, quality, or levels.

Will Soundtrack Pro allow me to master multi-track audio CD?

Please help! I have been looking for the past 4 days for a multi-track audio editing software that will allow me to burn multiple tracks to a CD. Here's what I'm trying to do: I have a 45 minute message and I want to fade a song in at the beginning, and another song fading out at the end. Then I want to place markers every 10 minutes, split into separate tracks, and burn the whole thing to CD from within that software (possibly I can fudge on this last one by exporting each individual track to iTunes, then making a playlist, but if Soundtrack Pro or some other program can do it all, then that is what I prefer!)
I tried Audacity, and it was close to what I wanted, but when I exported into iTunes the last 20 seconds of every song dropped audio! I have also tried the following and these are the errors/difficulties I encountered:
• Amadeus II : No multi-track mixing capability
• Cacophony: kept crashing, multiple error messages
• Jasmine: unique tape-style interface, but again, no multi-track export
• Sound Studio 3: good interface, easy marking, but no sound after export
• Snd Sampler: only one sound can be open at a time
• Deck LE: wouldn't even open one of my audio files!
So now my attention is on Soundtrack Pro and Logic Pro. Both of these seem like they will have what I need, but I'm going to have to fork over a pretty penny. Which is better and will either do multi-track mixing to CD?
Thank you so much to anyone who will read through my whole ordeal and help me out with their musical expertise and sound audio advice!
Sincerely,
Paul

Hello,
I thank you both for the help you've given, and I have obtained STP and really enjoy using it, but I am still disappointed that it will not allow me to master multiple tracks. For instance in Audacity, there is the export multiple command that splits one long song up according to the markers that you placed and then exports them as several different files. In STP, this same process is amazingly difficult, you have to take the razor tool, cut each section, drag it down to another track, then put a stop song marker after the cut section, then select each track and "export selected". (Do you know of an easier way?) Now for a $1200 dollar program that is just a little bit ridiculous, why cannot Apple just have a command to export by markers? Where can I go to request this feature be implemented?
Here's an example of what I am looking for, with features such as Redbook CD mastering (but this software is too buggy)

My video has no sound but i want to add the audio using premier pro

My video has no sound but i want to add the audio using premier pro.
when I want to import the file,it said:your video file has no audio.
But i want to add the sound to my video!!
Does anyone know how to solve this problem??

So you have a video (.mov) that some how you got from Flash.
It has no sound on it.
Does the .mov import into Premiere?
If it does..you edit it in the timeline (sequence) and add audio to the audio track(s) before exporting it.

Split Track Audio Output Problem

I'm trying to make a split track audio output as one requirement of the deliverables list on my current job. Dialog goes left, music right.
But even though I set up my sequence as two track mono, and have pre-panned the tracks all the way to the left (A1) and right (A2), I seem unable to make a quicktime that will play them as discrete tracks.
Inside Premiere, they play back properly -- A1 is coming out of the left speaker, A2 out of the right. No bleed or overlap.
I'm exporting them as quicktime, 2 mono tracks, ProRes 422. But when I play back the resulting quicktime -- voila, the tracks have been re-mixed together without my consent!
I've tried Media Encoder, with the same results.
FYI, In the "Channel Layout" section I've tried clicking both "mono" and "discrete" without any improvement. I feel like the problem might be that I'm choosing "Stereo" from the "Channels" popup, but there is no option for two channels that are not in stereo. It goes from mono to stereo to 3.
Any suggestions would be most welcome. Especially if they arrive soon! : )
(Using Premiere Pro 2014.1 on a MacPro Quad Core 2.93GHz machine with 16GB of RAM.)

i'm experiencing the same issue since today.
very loud (nearly ear damaging) glitches on crossfades on audio channel. doesn't matter if mp3, aif, or wav.
plus one channel of stereo sometimes randomly gets louder on transitions for a short time.
is still there in export. no matter if directly from premiere or via media encoder. (export as prores 422 with uncompressed audio). disabled native ppro import in AME, didn't help
cleared all media caches and preview files, didn't help.
not using preview files for export.
read alot about this bug being in older version here on the forums, but it is still there in CC 2014 v8.0.1
i am on osx 10.8.5.
please help Adobe.

Multicam editing with multi-track audio?

Does anyone know how to do multicam editing with multi-track audio? Apparently, the multicam editor can only see Audio Track #1 in the Source Sequence. I tried mixing my original audio tracks #1, #2, and #3 (submixes) to the master audio track in the Source Sequence and if I listen to the new Multicam Sequence (the nested Source Sequence) all 3 original audio tracks are there (combined), but when I go to do the multicam edit in the multicam monitor window, I"m back to just Audio Track #1 of the Source Sequence and audio tracks #2 and #3 are missing ??? Thanks for your help!

I have run the gambit of different techniques. The one that is most efficient is listed in Colin Brougham's response number 9
There's a far easier way to do this: after you sync your angles, hold down Alt/Opt and select or lasso just the video portions of the clips, and nest those. The audio stays put, but the video moves into the nest, and you can then enable Multicam on the nested sequence.
One of the best things about this is that it circumvents Premiere Pro's totally BS "Render Required Files" nonsense.
I must admit the ALT lasso tip was one of the best features I have seen. Like a revelation when I discovered it some months ago while watching a tutorial about something not related. As far as the "Rendering required files" That was kicking my but for a while doing multicam editing. If you do edit both audio and video in multicam you might find the "Rendering required files" issue. Basically the problem stems from having a lot of cuts to process at the same time both audio and video. 1080P is a huge amount of data when you multiply it by four cameras plus multiple audio cuts and effects ,(audio gain, Deessing etc.) So Pre-rendering the audio by clicking in the main sync timeline and then at the top Click Sequence/Render Audio.This takes care of the issue when you are cutting multiple tracks at once. It is a good practice to work from a main sync sequence and then copy that to a new sequence preserving the main sequence as unchanged. I found the solution is to "render audio" only in the master sync sequence this will then pass through to all subsequent copies that are made "downstream" allowing you to easily clean up anything. If you make a mistake you can always start from the main sync sequence and not lose too much time. Takes a little bit of time to render but once that is done you can cut all tracks video and audio like butter. I have been doing a lot of 1080p multicam editing over this past year and had quite learning curve. Most of the work I do is multicam editing by choice it is much faster for me to edit this way because I am used to working in live events where we need to look at all shots at the same time make a "best choice" and keep rolling. Have fun with it!

I am having trouble bouncing and creating an aiff file that plays back. I've checked my output settings, and although I am able to create MP3s, the aiffs are blank. The happens when I try to export a track as an aiff file - it's blank.

I am having trouble bouncing and creating an aiff file that plays back. I've checked my output settings which appear to be correct. Although I am able to create MP3s, the aiffs are blank. The happens when I try to export a track as an aiff file - it's blank.

When bouncing, do you use the Key Command or the button on the Output Channel Strip? The Key Command only bounces from the Stereo Output. The bounce button bounces from the Channel Strip it is on. So if you want to bounce out outputs 3-4 or higher, don't use the key command, but the button.
The strange thing here is that Logic, when it bounces an MP3, first bounces an AIFF, which at the end of the bounce process is being converted to MP3, so I can't imagine how you can get a silent AIFF and a normal MP3.
How have you listened to those bounces? iTunes? Quicklook? Quicktime?

Best program for mlti-track audio

Does anyone know what Adobe program would work to create a multi-track audio interface?
The idea is to allow a user on a website to select what tracks are played.
For example:
A four track audio file of a song including: track 1: lead guitar Track 2: Rythm guitar Track 3: Bass guitar Track 4: Drums
The user could select all 4 tracks...or, if they wanted to play along with a lead guitar...select tracks 2,3 and 4.
Can I do that in Flash? Or what would be the best program for that?
Thanks!!!
Dignon

I haven't used the Isotope plug-in, but I use Brian Davies' Denoise which is a stand-alone cross-platform program: I found it much superior to SoundSoap. It's available in a free trial.
Declaration of interest: I have no financial interest in this program but was involved in the beta testing.
Together with the same author's ClickRepair it's possible to get remarkable results: this sample of a noisy 78 was treated with both programs.

How do I create a split track audio recording (2 outputs)?

I am trying to create a two-output track for use with IEM and house sound (right channel with some instrument tracks to house; left channel with click & choral voices to IEM only). I don't know how to assign the output to L or R in Express. I've seen some online answers in Pro, but they don't work the same.

Maybe it's just me, but I don't want to have to think about instrument numbers when I'm creating music.
"Create with next" requires you to:
1) Highlight the last used instrument (highest by number)
2) Have another (n+1) instrument ready to go in your Environment
If you fail at step #1, you'll get a duplicate, and if you fail at #2, you'll get some other type of track entirely (maybe a bus, a master fader, etc.)
Maybe I'm old-fashioned or something, but when I want a fresh track, I just want a fresh track... I don't want to have to think about existing track numbers, or the state of the Environment That's why I use "Create" and "Create Multiple," and I haven't found much use for "Create with next."
But, hey, really, I'm glad it works for someone!

Can we capture the video and audio using cam and microphone in Edge Animate?

Hi Everyone,
I got a new requirement from the client to create a HTML5 based functionality through which one can capture the video and audio using his web-cam/camcorder and microphone. I have researched on internet and found that there is api available (not reliable) http://www.html5rocks.com/en/tutorials/getusermedia/intro/ . I am not a coder by profession and use Edge animate to create HTML 5 based animations and stuff like that. Another problem which i have found that the api only works well with Chrome and Opera and not with Mozilla, IE..
Can anybody help me out in this, please...
Thanks & Warm Regards
Vikas

Hi, Vikas-
After a brief bit of research, you're definitely hitting upon the limitation of the browsers. Not all of the browsers have implemented this part of the HTML5 standard, so you're going to either have to use Flash or be limited to these specific browsers.
Thanks,
-Elaine
