Some compressor plug-ins can be configured to expand, but I don't know of one off-hand... Maybe Audacity's compressor can do it... I don't know. Chris's Compressor can expand if you use a negative value for "compression ratio". Steve did make a "peak processor" nyquist plugin wh...

I tested recording using the Windows Sound Recorder. Here are links ... WMA - https://www.dropbox.com/s/beb4ieq95gdmewe/Untitled.wma?dl=0 This was with the mic level at 50%. It sounds to me like the hiss is still there, but I haven't been able to figure out if it's quanitized... The hiss noise on t...

Here's a crunchy one from 1923 ... '' I'm Broke Fooling With You'' 1923 , before-after de-clicker settings shown, (no other noise reduction).flac De-Crackle settings (compromise, processing is 4x playback time).png The settings are a compromise : trading off DeCrackle against processing time. The se...

Fixing spikes in a signal may actually be a different problem from fixing small natural sounds of short duration ... DeCrackle looks like the DeClick problem but on a smaller time-scale, so a DeClicker will also DeCrackle, but inevitably involves a lot more computational effort because the occurren...

You have to label the parts of the track you want to split , then Audacity can export each labelled section as a separate file , (automatically numbered if you want), using "export multiple".

export multiple can add automatic numbering to file names ...

Re: DeClicker ... it's also a DeCrackler if you push it to the max ... Now the bad news ...
processing to DeCrackle takes about 10x the playback time on my 5 year-old dual core computer,
(your mileage may vary).

Thanks! I have noise removal at 25 (the top slider). What should I lower it to? 10 is a typical value for me, you should use the bare minimum of noise reduction. There should still be a hint of hiss-noise between words rather than total silence, as the onset of speech after total silence is jarring...

As the video explains, I'm looking for A) what is causing the noise? Is it mouth noise, a mic problem, a connection problem, something else? It's not digital , it's mechanical : the diaphragm of the mic occasionally sticking and freeing itself with a click + ring. IMO microscopic blobs of saliva hi...

Actually, is the mere presence of a track that is 16000 Hz going to stop me from ever pasting something higher quality in? The project sample-rate (shown on the bottom left corner of Audacity) determines the highest possible quality of the show when it is saved ["exported"] as a WAV file....
