Stuttering in Voicetracking

English General
1

I can voicetrack in the database without any problems. When trying in the studio playout I get missing pieces of audio - amost like someone has edited certain parts of the voicetrack…any ideas?

I would first check whether the stuttering occurs during recording or during playback. You could open the recorded audio file in an audio editor for example.

Hi there,

Have you tried increasing the buffers for recording?

Thanks for the quick replies. I am getting the error “pre-buffer timeout” even though I have increased the buffers. Any ideas on what the buffers should be set at. Is it to with RAM (3Gb on this machine).

The message “pre-buffer timeout” appears when the recording sound card fails to deliver the recorded sample data fast enough for simultaneous playback.

Example: The buffer size of the mic monitor (playback) sound card, which is determined by the buffer size you enter in the config and/or the latency reported by the sound card, is 100ms. This means that when playback/monitoring is started, mAirList will collect 100ms of recorded sample data before actually starting playback. It will wait at most twice this time, 200ms, for the data to arrive, to avoid lockups caused by broken sound cards.

So the steps are:

  1. Start recording into buffer.
  2. Wait until 100ms of sample data are in the buffer.
  3. If less than 100ms of sample data have arrived in 200ms time, stop waiting and display a “prebuffer timeout” error.

So it looks like something is wrong with your recording sound card. What audio method do you use anway, DirectSound, WASAPI or ASIO?
