I am on a new Mac Studio (Apple Silicon) running Monterey OS 12.3.1.
My Audacity app is the latest, 3.1.3
I was told it would run fine on the new Apple Silicon chip (through Rosetta) so my first question is if that is true.
If Audacity cannot run yet on the new Apple machines/chips, please let me know.
If so, my question pertains to integrating Audacity’s ‘effects,’ (reverb, delay, etc.) into a QuickTime Movie recording, or into iMovie.
I am recording straightforward videos at my desk, with a USB microphone for my audio input and a webcam for video. I record myself against a green-screen, then import the finished project into iMovie for further editing.
I simply want to add effects like reverb of various room-sizes to the spoken audio, with control over dry send/wet return. QT has no add-on effects, and iMovie’s 4 room reverb effects choices are horrible, with no dry/wet balance control.
Can I use Audacity for this? Either pre-input, as the mic audio input is being recorded into QT, or post, ‘on-top-of’ the audio in the completed QT movie?
I’m a Windows guy so I don’t know about Apple Silicon…
Audacity can open the audio from an audio/video file but for most formats you’ll need to install the FFmpeg import/export library.
Then you can edit-process, export the audio, and most video editors will allow you to replace the old audio track with the new audio-only file. Export as WAV if your video editor accepts it because it’s probably going to get re-compressed again when you export the audio-video file.
Of course you can’t cut & paste or do anything that changes the timing or length of the audio while it’s separated from the video.
And some of the highly-compressed audio/video formats have a tendency to go out-of-sync when you split and then re-multiplex the audio.
Thanks DVD Doug, installed FFmpeg, which Audacity located immediately on restart. Exported audio from QT file (no choice to export as WAV file, automatically exported only as m4a file.) Added effects (reverb) and re-exported as mp3, then drag/dropped into QT video and it immediately played the audio back with the effect!
Sync between voice track and video of speaker remained intact.
And you are correct about needing to do all cut/paste changes prior to exporting the audio and processing, since that’s unavailable after re-importing.
My only remaining question is: Audacity’s 3 general export choices are only Export As>MP3/WAV/OGG. However, if I select Export Audio, I get a separate window with many more choices:
including AIFF and M4A AAC
Which would you suggest I use when I drag the ‘effected’ file back onto the video
