Software to clean up a digital minidisc recording?

Post by Jim Cohen »

Using my new Sony Minidisc recorder (thanks, guys, for all the advice!), I just recorded a Bach cantata that my wife conducted at a church this morning. It came out great, with the exception of one spot where it appears someone banged into the mike stand or something that made a loud noise.

Is there software (free-, share-, or paid-) that I can get to clean up pops, bangs, etc. from a sound file like that? To put it into my computer, I'll have to send it as an analog signal, and record it as a wav file, but then can convert it into an mp3 to work on digitally again. Any suggestions?
Thanks,
Jim

Goldwave will do that. I use it for my "mastering". I run my mixed down songs into the computer and then use Goldwave to clean it up, compress, balance tracks, etc. www.goldwave.com


This belongs in computers

Jimbeaux,
Basically, what you need is an audio editor. As Jack points out, there are some excellent shareware products, like GoldWave and CoolEdit (which I prefer over GW). The best software I've found for editing is SoundForge, but it is rather expensive -- at $500 or so it's probably overkill for your application.

BTW, you don't generally EDIT in the mp3 format -- you record to the WAV (PCM) format and do your editing in this uncompressed format before converting/compressing to mp3. You can get 5-10 fold compression (at 128 bit or so).

Whatever software tool you choose, the most important audio manipulation is called 'Normalization'. You can either set the highest peak to 100% or can apply RMS compression which gives you a 'fatter' waveform. If you normalize all songs to the same standard (peak or rms), they will all be about the same volume on the CD. May not apply to the cantata unless there are separate songs or movements you choose to save as individual tracks, but useful for future reference.

In all of these sftwe pkgs you can view the actual waveform and edit out those coughs or micstand accidents with pinpoint accuracy.

Let me know if you still have ???????

I'm also interested in the live CD when you get it mixed down. Sounds like a killer set of tunes. Image
