I just came across a great quick tutorial from Total Composure on YouTube. By using ReaFir in subtract mode you can remove any constant hiss and noise from your recordings. It may not work as well as iZotope RX2, but it’s an impressive free option.

That’s a great tut. Didn’t know this function so far. I’m just gonna try it ;o)
This application works pretty well, and closely mimics the Sound Forge ‘Noise Reduction’ plug-In. Having used both for a while now, I’ve found that by lowering the amount of ‘noise reduction’, re-sampling the file and repeating the procedure a few times results in a more transparently-processed final file. Thanks for the tutorial – well done.

@Rob I didn’t have much luck with it myself compared with iZotope RX2 (basically magic). But you got me thinking about it again. Instead of resampling why not a few instances of ReaFir in the chain?
I’ll suggest that a few instances in the chain ‘repeats’ the same noise sample removal a number of times – whereas multiple re-samplings may ‘catch’ alternate problems as the signal is ‘cleaned’ – I think too, used in moderation, my method is less likely to introduce objectionable anomalies onto the original sounds. And yes, iZotope is better, but it’s not as ‘cost friendly’ as Reaper – which is, BTW, a product I highly recommend to all of my students.
ReaFIR #2 should be using the noise-reduced output of ReaFIR #2, rather than using the same noise capture for both.
I try to avoid destructive editing as much as possible and I think that might be a free way around it.
I’ll have to try it.
