Chain export high sample rate mp3s from wav?

[mishagos]

Hi,

I'm trying to chain convert/export files that have a very high sample rate (96000) from my Zoom Q3. I want to basically batch convert the wav files, which works fine except that the high sample rate requires me to answer a dialog box (invalid sample rate for mp3 ... reset to... 41000? [yes]) rather than being totally automated and letting me go do something else while it's converting.

I've tried playing with editing and creating chains but I can't seem to figure out how to make it automatically do that step. Suggestions?

The high sample rate also prohibits using various freeware like Any Audio Converter because they choke on it.

Thanks

Ian

I don't think that you will be able to do it with Audacity. Perhaps you would have more luck with SUPER (a free converter by erightsoft) or Foobar2000 (a free music player/converter)

I've moved this to the correct forum for 1.3.x - 1.2 where you posted does not support chains.

Audacity chains don't let you set the sample rate or auto-accept prompts - we'll add your vote.

48000 Hz is the maximum allowed by the MP3 specification so you will have to convert the files to 48000 Hz *WAV* before running the chain; or import each file into the project and run the chain on the project; or use a script program like Autohotkey to take action when the "Invalid Sample Rate" dialogue appears.

Thanks Gale. I like the idea but AutoHotKey has me confused. Are you familiar with it? Can you tell me what to do to get that to work, i.e., hit return for any popup in Audacity?

Thanks!

No, I'm not really familiar but you probably want the WinWait function followed by {ENTER}:

You're only waiting for the "Invalid sample rate" dialogue, by the way. I don't think any other prompts will interrupt the chain once started. You could always ask on the AutoHotkey Forum if you're stuck.

I think it depends if your chain is running effects on the file. If you are just converting from one format/sample rate to another you might just as well use SUPER.
