Stretching audio in FCE

I have a video file of a brass band performance that I have put into FCE. However the audio quality is not the best, and want to replace it with a separately recorded audio file of the same band playing the same music. I have dropped the new audio in place, and sync'd its start with the video and old audio.
The problem is that this audio recording is approximately five seconds shorter, start to finish, than the same track on the video. What I want to do is stretch the new audio track by those five seconds to make the track lengths identical. There does not seem to be a way to do this in FCE, but I also have Audacity, Amadeus and a couple of other audio processing programs, and what I read says time stretching can be done in Audacity. However, I cannot figure out how to do it, and the "manual" is no help.
Does anyone have a procedure for doing this that they would like to share (in some detail, please!)?

There is also Amazing Slow Downer" which can slow a piece of audio without altering the pitch.

Time stretch audio file to match tempo of track

Hi everyone, I am a new user of Logic express, and have found the info on this site extremely helpful, in conjunction with SFlogicninja's tutorials on youtube.
However, after watching a recent tutorial on Time stretching audio, i am now completely confused. Similar to the tutorial, i am trying to fit an audio region(an acapella track) to the tempo of the project. I have beat mapped the region to establish a tempo, but would like to experiment with slowing down or speeding up the track as a whole. As the acapella was created outside of Logic, i am bouncing the acapella track in order to be able to 'follow tempo'(as shown in the inspector). I have disabled the 'normalize' checkbox and bounced, but the bounced track still does not have the 'follow tempo' option in the inspector.
Any ideas as to why my bounced files cannot follow tempo. I can do it with audio that i create in Logic, but if i import any files, i was under the impression that by bouncing it within Logic, i could still obtain the same results?
I'm running out of hair to pull out!

Hi
Seems to work OK here

Did I understand correctly that just by ""renaming"" Logic 9.1.6 inside the application folder it will keep it functioning in case I wanna revert to it later??
Yep (but you will probably still need one called "Logic Pro" to get Software Update to see it)
I have mine setup to quickly switch from 32bit to 64 bit (2 copies with different names) and also previous versions.... works fine

Get rid of the warnings prior to stretching audio in Arrange

Does anyone know how to get rid of the warnings prior to stretching audio in Arrange?
In the demonstration here on Apples own website, workflow is sped up by the fact that you don't have to hit ok twice before the edit is executed. I have tried to disable warnings etc, but it still does it.
http://www.apple.com/logicstudio/logicpro/
Incidently, I clearing popup warnings using the V-Pots on the Mackie Control doesn't work anymore either. Can anyone confirm this?
This appears to be yet another newly introduced controller bug... Don't even get me started on trying to use a Frontier Tranzport with version 8.

No, the inly option is to uncheck 'Warning before processing function by key command', which doesn't change the situation.
Have you actually done this?

How can I ONLY capture AUDIO in FCE 4?

How can I set my FCE 4 capture setting to ONLY capture the AUDIO from my video tape?
I only need to the audio, and don't want to bother with the video in order to save space
thanks very much

Final Cut Express does not support audio-only capture. Never has. You can only capture video+audio.
I suggest capturing the video+audio. Then in FCE place the entire clip in a sequence, unlink the audio tracks from the video track and then export the audio track to AIFF. Once you have your audio file you can delete the video clip from your hard drive to save space.
Alternatively, connect the audio line out from your device (a VCR?) to your Mac's audio line in and record the audio in QuickTime or any audio editing app. Keep in mind that if you plan to use the audio in FCE it needs to be AIFF, 16-bit (aka 48KHz) stereo.

Converting Audio to FCE

I am trying to import a song from iTunes to use in a project, knowing I need to render or convert audio. FCE 4.0 will let import older songs that I put in iTunes some weeks, months ago, but not three songs I've just loaded through a CD. Those newly loaded songs have properties of iTunes 8.0.2 and Quicktime 7.5.5. I wonder if there is something about new iTunes update I recently downloaded that is not allowing me to import them into FCE. Any help on how to get these into FCE would be greatly appreciated. (when I try to import, they show up as faint type and won't allow me to click on them.

All music bought through ITunes is DRM protected ( copy right ) and, cannot be used in FCE.
The music you installed into Itunes via CD is not DRM protected however, copy right laws still apply.
To use the non-DRM music from ITunes in FCE you'll need to convert it to an .aiff format

Burn Audio CD and Time Stretching audio - software on the iMac?

I have a new iMac 24 running OSX 10.4.9 and had two questions:
1) Is there software on the iMac for buring an Audio CD? Created a song and I am trying to figure this one out.
2) Is Garageband able to time-stretch a song? I need to edit some performance songs that need to end at a specific time. I use Sonar on my PC to do this but wondered if Garageband or another utility on my iMac could handle this.
Thanks!

1) iTunes will do that (not GB). Just create a playlist and click "Burn Audio CD". (That's the default setting.)
2) GarageBand can do that, but you'll have to play around a lot to achieve it. I'd recommend an audio editor like Audacity or SoundStudio - there you can change the tempo of a song (without affecting the pitch), and it will tell you immediately how long the result will be.

No audio in FCE with Canopus ADVC-110

Working in FCE HD 3.5, when I try to capture VHS from my VCR through the Canopus ADVC-110, the video is captured, but no audio. No audio appears on the audio tracks. When I do the same in iMovieHD, both the video and audio come through clean and clear.
I have the easy setup in FCE set to DV NTSC DV Converter. (Same thing if I have it set to DV NTSC). Any suggestions? I'm on an iMac 2.16 Intel 2GB, with a 500GB external hard drive.

I'd try shutting everything off completely, removing all cables and then start from scratch.
FCE should be able to import using the DV Converter option.
I suspect some king of weird fluke like cabling that the audio didn't arrive.
If that does not work then try trashing the FCE Preferences. Otherwise, I'm stumped as well.

Rate Stretch audio goes out of sync when exported.

Audio, which is rate stretched using the rate stretch tool to 100.01%, plays fine in Premiere Pro CS6. However, when exported to Encore or to MPEG-2 file, the audio is no longer stretched and becomes out of sync by the end of the video. When I play the preview in Encore, the audio is out of sync. Switch back to Premiere, it is OK. Export a MPEG-2 file and author a DVD, the audio is out of sync. Go back to Premiere, it is OK. I record the audio using a TASCAM portable recorder. I have recorded and synched audio many times and this is the first time that it does not work, on two separate Premiere projects. Any ideas on how to fix this. Even better, is there a way to record audio so that it matches the video (from a Panasonic HD AVCHD camcorder) without requiring rate stretch adjustment?

Try changing the speed with right click, Speed/Duration instead of using the Rate Stretch tool.

No Audio Playback FCE

Okay, I shouldn't have said 'no' audio. I hear FCE through the system but nothing thru my soundcard.
System Prefs are correct. All other apps follow the setting. FCE is always system.
The control panel for my Delta 2496 shows a sample rate of 44.1 and doesn't accept changes.
FCE's Easy Setup for DV-NTSC lists 48 khz capture and Audio output is to FW DV.
Do I have a sample mismatch or is the audio looking for a Firewire exit?
Thanx
Dave

Go to your FCE menu - you should be able to make a choice for AV devices and tell fce to play the audio out through the card.
If it isn't there - it'll be somewhere else.
Sorry, haven't used fce - this is the fcp forum.
btw - I headed over to M-audio site - it says you can set sample rates etc;

Cannot import audio to FCE from mpeg files on desktop

I have videos from Streamclip mpeg 2 files that work fine when played on Streamclip (video and audio) but when imported into FCE for editing there is no audio. The audio box is checked but greyed out in system settings. Is that a problem? MAC Snowleopard.

OK. I was told when I bought FCE that I needed Streamclip MPEG4 ($20 from Apple) to first transfer all my VOB's and any videos I had into streamclip then take those files to FCE. As I say these videos play video only in FCE but play video and audio in streamclip and DVD player.

Cannot import audio into FCE.

I'm trying to put my svhs video tapes on my harddrive. I am using the Pinnacle Movie Box DV from the VCR then Firewire from Movie Box to Macbook Pro. I get the video but no sound. This also happens in Imovie, but in Quicktime pro I get both the video signal and Audio signal. I have also tried connecting the line in and the same problem occurs, but again its ok in quicktime. It doesn't seem to be the moviebox problem, its just that Final cut express/Imovie is just not getting the audio portion. This the first time I'm using FCE or Imovie. There must be something I'm not getting. I need to get this video onto my hard drive before I lose all these memories. Please help. I've tried asking this on many forums, alot of peeps, but no answers.
One more thing... What would be the best format/file type to record to. For now, all I need is to save them to the harddrive to edit at a later time. I was thinking H.264.

Ok that worked. I clicked on Easy setup
Formats: (all formats) Rate: (all rates)
Use: DV-NTSC DV Converter (Whats difference between that and DV-NTSC BASIC) ???
Then Clicked on File
Scrolled down to New Project and then capture. WORKED thank You.
Now I'll have to figure out the program but I'm sure I can do that. One more question... What format should I save it in? H.264, AVchd etc? At the time I just want to get all the video tapes onto the harddrive, then in the future, edit them and maybe get them to dvd/and leave them as files for future formats.

Un-stretch audio?

Hi
I stretched an audio file a while ago and accidentally deleted the origional file.
The action is not visible on the undo-history.
I guess the only way I have is to un-stretch the file and try to listen...
Anyone know if a way to see how much a file is stretched exist in LPX?
thanks

Actually the term "extract audio" is misleading.
It just copies the audio from the clip to a separate audio track and mutes the original track.
So to un-extract audio you just need to delete the extracted audio track and un-mute the original clip's audio.

Time Stretch Audio in FCP?

I've got a sound I'd like to time stretch on a simple project. I'd rather not have to do anything in STP since this is the only sound I need it for--is there a way to stretch in FCP?

Hello Mr. Wolsky,
I have read many of your extremely well informed posts on this site and greatly respect your opinion. I am wondering, however, if you are perhaps mistaken in stating that one cannot pitch shift in FCP.
I invite you to go to the Apple Sound Effects Plugins folder and take a look at "AUPitch". I have used it often for making Foley sound effects that I either can't be bothered to search out - for instance a huge metal clanging door I pitch shifted up a few octaves and it became a briefcase lock springing open.
I think people just don't look in that folder because it looks kinda boring.
Here is an extract from an article on Ken Stone about the Apple audio filters.
Hope this helps.
Harry.
AUPitch
+Adjusts the pitch of your audio, obviously. There are a LOT of controls though, and I have to admit that I don't have a clue what a Glb Trigger Thresh or a Loud Aggr K is. Effect blend blends the pitch-shifted audio with the original and is sometimes necessary to make voices sound natural. It is worth mentioning that I've gotten perfectly acceptable results by adjusting the first two parameters and not bothering with any of the others. I'd imagine that most people wouldn't have to adjust more than these.+
+I tried a Google search on some of these parameters but they only turned up forum threads where people were asking what on Earth they meant and no-one was able to solve their problem. If anyone does know, I'd be interested to hear from them.+
+This can be useful for making a male actor's voice more masculine (yes, I have had to do this!).+

Why no audio in FCE?

I have used FCE for about a week in preparation for some projects, and suddenly the audio does not seem to work (capturing captures the video from a camcorder, but nothing is heard.) My computer sound prefs are fine, and CDs play. QuickTime files play UNTIL they are exported into FCE. Did I accidently turn on/off in the interface that would do this?
Thank you very much in advance,
George Bartley

When you are capturing you cannot hear the audio on your computer.
However, once it is captured you should be able to hear it when you play your clips back.
If you can't hear the audio when playing back clips, try this - select View>Video Out>Canvas Playback.

No audio in FCE

hi there!
i´m really a bit desperate here... when i am reading my material from camera to FCE, there is no audio. this is akward since i already tried it in iMovie and it works perfectly there.
i searched all settings in FCE, i read tfm, but i can´t find anything that helps me out here.
i´m working with FCE HD 3.5.1 in OSX 10.4.10 on an iMac 2.16 GHz Intel Core 2 Duo.
please help me, this is driving me nuts.

The Audio setup is grey and cannot be changed - that is normal.
Is your Easy Setup correct ?
For normal DV it should be DV-PAL or DV-NTSC according to what your camera uses.
Whenever anything unusual starts happening in FCE the first thing to try is trashing the preferences.
Follow the instructions in this link:-

Note that you may have to reset your Easy Setup and any other special changes you have made as everything reverts to the default settings.
