I imported a Instrumental song and i just sang to it , and i exported it and when im playing , my voice is slower than the music , but when singing it was ok . , this happened to me in JET AUDIO - Audio mixing recorder also , can anyone help :smiley: ,Sample rate was 44.1 in both ,is it the slower in MIC ? , The instrumental was normally played but my voice is not going simmiler as i sang :smiley:

Sorry for my bad english

Try setting the sample rate to 48kHz - it could be that your sound card does not like 44.1kHz

If that does not work, please give more information. Tell us about your system, tell us how much slower it is playing.

i tried setting the rate to 44000 ,so then it starts correctly but when the time goes when playing ,it again going fast

Do you mean 48000 ?
How much slower is it playing?
Are you using an on-board sound-card?

My new workaround. Open audacity. Start recording for a second or so. This will exhibit the slow playback problem. Then delete the track and start recording again. This track now plays back at the right speed.

You might have a driver problem, or maybe there’s a bug in JetAudio.

It’s the driver’s job to communicate the sample rate between the hardware, software, and operating system. As long as “everybody knows” what the sample rate is, the speed & pitch will be correct and sample rate errors are rare.

You can get sample-rate mismatches with S/PDIF devices because these don’t communicate directly with the hardware. Only the audio data goes-over the S/PDIF connection.

Or, every soundcard has it’s own clock (oscillator) and no clock is perfect. So sometimes you record on one device (such as a USB mic) and playback on another device (your soundcard) and there is a pitch/timing mismatch. But, that’s a hardware problem and so wouldn’t explain your issues and it wouldn’t self-correct when you start-over.
