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

So, I won't be using his camera in the future since I plan on using other live performances of mine for my website and other CD's, and I will only hire professionals to record these performances. If you do have simultaneous amateur-video and a professional-sound recording of a performance it may be...

Re: make loud noises quieter

I have an audio import from a blu-ray movie that import to several mono tracks. I mixed and rendered to one track, and have exported to mp3 … My problem. When I am in the car, I can just barely hear the audio at full volume. But then *BAM* - a dog barks or someone in the film slams a door and the n...

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

Sorry to be “Simon Cowell” here but IMO there is no way of fixing that intermittent distortion. Not noise reduction, notch filter, equalization nor Holy water will cure it, sorry. It’s a milder & less frequent version of the distortion corresponding with the bass which occurs with bootleg rock c...

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

"Change Speed" to -19 Drastically lowering the speed has cut the high frequencies and with them high frequency distortion. But you’d be better off cutting back the high frequencies using the equaliser rather than slowing speed or pitch shifting … Porgi Amor Test, before-after bass and tre...

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

I've just listened to Trebor's rumble enhanced clip and the sound I hear on my car CD player is just like that only not so pronounced The rumble enhanced version was a visual demonstration of the association of singing distortion with bass piano notes: meant to be seen as it played on Audacity. How...

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

I still think the piano is causing the distortion but I've changed my mind about AGC being the cause. The distortion in the singing corresponds with bass piano notes (and the changes are too snappy for AGC). If you compare these waveforms ... http://forum.audacityteam.org/viewtopic.php?p=117901#p117...

Re: FM Stereo "noise" and its removal

... It's gone as mysteriously as it appeared a few days ago. If the noise is intermittent on one receiver then we can exclude ripple, as that is never spontaneously cured. ... I will try David Sky's notch filter that Trebor suggested. Sorry but a notch filter won't remove that type of noise: a notc...

Re: FM Stereo "noise" and its removal

interval between bursts of noise is 0,02sec ie 50Hz.png The noise is bursts are 0.02 seconds apart, i.e. 50 Hz , the mains frequency (in the UK). A possible explanation is that the components (capacitors) which smooth the power supply in your 18 year old audio device have started to fail and 50Hz r...
