Re: Amplifying very very low audio

I tried straight amplification. 40 dB and it is audible, but the hiss in the background make it impossible to listen to comfortably. The words can be made out. My suggestion would be to remove all the frequencies above 4KHz to reduce the hiss, then amplify. Audacity's equalizer, in "effect&quo...

Re: Clipping or Distortion on Vocal High Notes of Ripped Aud

Here is the promised 6 Second Clip. The note is an "E". That has distortion from clipping, (something is turned up too high) . I've had a go at improving it, but I've just exchanged one form of distortion for another ... Oh, Quand Je Dors-6 Sec Clip_before-After-.mp3 Sorry but IMO the onl...

Re: Is my recording level too low? Is my amplified level ok?

On Ezekiel000’s screengrab each section is consistently offset, but some sections are negative some positive: an ultra-low frequency alternating signal could cause that presentation (say 0.001Hz , peak amplitude 0.2) , however the equalization I suggested, removing everthing below 20Hz, would have c...
