A techy question re mp3 file creation and playback
Hello, When I record NLS tapes, I create .wav files at 16000 KHZ, 32 bit using Goldwave 5.10. Then, to compensate for the double speed recording, I change the sampling rate to 16 bit so the recordings will play at normal speed. On a couple of occasions when creating mp3 files with C D E X, I remember encountering a situation where the mp3 file which I had created played at either half the recording speed or double the recording speed, I don't remember which. So the question is this--Using C D E X or some other program, is there some means by which I can create an mp3 file and then play it back at half of the speed at which it was recorded? One word of clarefication: I am not talking about bringing the mp3 into GoldWave and then down sampling. I want to record the mp3 at double the rate on which it can be played in Winamp, Total Recorder, or some other program. I hope I get some meaningful feedback on this because I want to streamline the recording and playback process as much as possible. Thanks in advance for ideas.

Hi, Donald, Are you sher you're telling it right? The bit rate has nothing to do with the speed, the sampling rate does. The bit rate deals with resolution of dynamics and such. Instead, is this what you do: you record the nls tape at twice the normal speed and use a sampling rate of 32000, 16-bit and then, save the .wav file as a 16000kbps sampling rate and still 16-bit? Once converted to .mp3, that file would then play back at normal speed. Jay - Original Message - From: Donald L. Roberts [EMAIL PROTECTED] To: PC audio discussion list.

Re: A techy question re mp3 file creation and playback
That's it, Jay. Please go by what I mean and not by what I say. Actually, I have one player which will play NLS tapes at four times the actual playback speed. And if the tapes are well recorded with good high frequencies, I will sometimes do them at 60 thousand Khz and then down sample with Gold Wave to 15000 which still sounds reasonably good, although certainly not high fidelity..
