…I first tried using the “Normalize” filter setting to "0dB" as Trebor suggested, but that increased the volume and wave form too much. Normalize to 0db is maximum loudness , if that’s too loud replace the “0” in normalize with a negative number like “-3” , “-6” is quieter still , etc. … ...

If the sermons don't contain music, just speech, you can half the sample rate to 22025Hz, which will reduce your file size. Not for MP3, though - the sample rate does not affect the file size. Sorry I was thinking WAV , a constant bit-rate mp3 isn't going to be smaller by reducing the sample-rate :...

This project is for science fair. My science fair hypothesis is the effect of the diameter of a microphone on the amount of static, or noise interference it has. I've already bought different microphones based on their diameters ... The more sensitive a microphone the better the signal-to-noise rat...

Swap Left and Right (chanels) does not appear in my track dropdown bos. Using Auacity 2.0.5. Any ideas? Select "Split Stereo to Mono" from the drop-down track menu, (see below), then either move the lower track up , or the upper one down , then select "Make Stereo Track" from th...

Koz, Understood. I have updated my personal documentation with your notations regarding using the default settings, and the issues that could arise if the noise or hum was above 7kHz. As you said, "cut off everything above about 6 or 7KHz with the equalizer" That was me (Trebor) who said ...

I cannot seem to see a listing for a second filter? And if not, what is the file name assigned by Audacity, so that I may locate it as well. I think Steve's is named "Hum Remover", you do have to unpack the zip file to obtain the text file with the name "de-hum.ny" , it's this &...

I just got an information message dated 2010 about forum "migration" , screen-grab attached ... Not a problem for me, I just though I'd mention it as it could be a symptom of something wrong with the forum.
