Chattering audio record

MBP 15" Late 2011 2.5ghz i7, 16gb ram, v10.10.1, Audacity 2.0.6

When recording using Dante Virtual Sound Card, audio always chatters or stutters. I do not have this problem when using internal sound card, MOTU Ultralite or Traveler, or M-Audio Fasttrack Pro. I have tried altering every setting in Audacity, Audio Midi Setup, and DVS. Any suggestions?

Do you need to use “Dante Virtual Sound Card” ?
What are you trying to do?

I am playing back audio using QLab through Yamaha consoles using Dante, and I often need to record voiceovers and other program. As a note, I just downloaded Sound Forge Pro for Mac, and that does not chatter.

Check that the sample rate is set the same everywhere.

Sample rate is 48k/24 everywhere. Record still chatters.

Please try not to use abbreviations.

Does MBP mean MacBook Pro?

“/24” means bit depth, correct?

Exactly which recordings chatter? Recordings of audio playback, if so how are you recording audio playback? Recordings made with your mic?

Are the glitches in the recording or in playback of the recording, so that the glitches are in different places each time? If in playback, what device are you playing to?

Audacity does not officially support Dante or any other networked audio, so you take your chances. That said, did you try changing “Audio to buffer” in the Audacity Recording Preferences?

Also you could try the latest 2.1.0-alpha from the top of http://www.audacity.homerow.net/index.php?dir=mac/&sort=date&order=desc. If it’s a playback issue, that might help.

Yes, MacBook Pro 15", and 24 bits.

Any recording made with any source through Dante Virtual Sound Card chatters, and only when recording. Playback of any known good audio, no matter what format, sample rate or bit depth does not chatter. I

have just changed Audio to Buffer to 50 milliseconds, and that seems to have solved the problem. Many thanks.

Thanks for letting us know. Was that still in 2.0.6?

If you update to 2.1.0 when it comes out towards the end of the month and the problem returns, try increasing the buffer again. I don’t think that will happen but it might do if you are playing audio in Audacity while recording.
