Trebor - So the workflow would be to add effects, etc then run the "no infrasound" then compress that particular track?? The infra-sound has to be removed before any compression or other processing is applied: unfortunately removing infrasound from the final mix won't correct the fluctuat...

Audacity spectrogram showing only hiss noise, no voice, above 6KHz on your recording , which was removed with the equalization shown in my previous post

Well I did use Steve’s Hum Remover and it did improve the audio, but I’m still hearing quite a bit of hiss in the recording? A side-effect of my dehummer is that it attenuates the higher frequencies , (where hiss lives), this is a beneficial side-effect in your case as your tape-recordings only hav...

The obvious next thing is what if it is not in the range requested. What is it that determines the RMS? The RMS value is an average value of the amplitude (level) of the audio waveform. RMS is proportional to the total area between the waveform and the zero line , (the red area ) Sine_wave.gif http...

... Measure between -23dB and -18dB RMS ... The " contrast " option in the Analyze menu will measure the RMS of a selected section of audio ... Select the audio you want to measure and click on the button I have coloured green, the RMS value will appear in the box I've coloured yellow ......

... I did compress each track ... If the infrasound was not removed from the vocal-only track and compression was applied, that could account for the vocal volume abnormally fluctuating : the vocal waveform is superimposed on the inaudible low-frequency infrasound waveform. If dynamic-range-compres...

the subject speaks almost with an Aussie twang where a statement will sound like a question. http://en.wikipedia.org/wiki/ H igh_ R ising_ T erminal There are free autotune plugins which work in Audacity which can limit the range of frequencies voice can occupy , even make speech monotone , but the...

Trebar....what did you do to help the vocals in the .flac file? I did it manually with the envelope tool : where the the vocal was suddenly too loud I made it quieter ... Envelope tool Demo.gif ( that manual process would take ages to apply to the entire track). The frequency content on your track ...

... Reminds me of underwater audio... Just noticed that it only contains frequencies below 10KHz , which partially explains the underwater quality. Possibly a sample rate of 22KHz has been accidentally applied , maybe via a too low a bit-rate if it's an mp3, ( using too low a mp3 bit-rate can force...

What's magic about listening? I get a loading circle animation forever. Koz The Reverbnation link worked for me. Musically it's very good, only problem is sounds like compressor-pumping : ( should apply compressor to each track individually rather than to the final mix ). Koz if you have something ...
