Audacity Forum

Trying to import/export M4A files. I tried the alternate method with no luck. Yea, I thought LAME was not for M4A's but that's what it seemed to be looking for, so that's what I was trying to give it. Got FFmpeg installed from a different app and Audacity didn't like/recognize that either. Followed ...

I can't export/import due to Audacity not being able to see libmp3lame.dylib, even though it is right where it should be, I point Audacity to the file, I do everything but rub it's nose in it. What am I missing here?

That would be a nice convenience.

Some exports don't have any idea what you want ahead of time. If you export WAV Microsoft signed 16-bit PCM, it should always add the .wav extension. I think there is another way to export WAV that doesn't. Presently, I am exporting to .M4A. I think that is the same setting I used previously but no...

Got it. Thanks.

DC offset (if you have it) is a result of a faulty or poor soundcard, a small (sometimes large DC current) is appled to the signal, sometimes just one of the channels. It shows up visually as a waveform that is not centred on the zero centre line. Is there a way to test for the presence of the DC o...

When 78rpm reaords were made, each company used its own equalisation curve, until they were standardised by the RIAA in the 1950s. Well, it sounds like I'm just gonna have to shoot in the dark and hope I get close on this one. It's been awhile since I've looked at the 78's that are the special proj...

Specs say it does have an optical digital input. But it is apparently in the 3.5 MM form, a combination input for both digital and analog. It's all a bit beyond me..

Okay, good to know. But I am curious about what DC offset is...
