No Xruns or Sound Anomalies While Recording or Play Back. But the Exported .wav is Useless.

Hi, I feel like the wind as been kicked out of me. No matter what I try I still have sound glitches in the exported ,wav.

I am not using plugins when exporting,

I have searched the forum here and others on setting up my DAW to get the most out of it.

I am not a linux or computer guru but should have an adequate system for ardour.

I am out of googled ideas and solutions.

Some of my specs:

Hp Pavilion a1350n
AMD Athlon™ 64 X2 Dual Core Processor 4200+
3 gigs RAM
Delta 1010lt

I am using ardour 2.3 (built from revision 3107)

Please let me know what other information I can give that will be relevant in finding a solution.

Thanks Philip

  1. please export a small part of the session and post where we can download it from
  2. please post the relevant .ardour file somewhere where we can find it
  1. Noise_Sample_Export.wav

  2. Noise_Sample.ardour

Thank you for the response.


Sorry Paul did not intend on creating a wild goose chase here but that is what it turned out to be. Unless you saw something in the .ardour file that revealed a need for correction.

I was playing the exported .wav file using vlc player. I started documenting the time and place of the noises I heard.

And noticed the skips in playback were not consistent. Vlc is not decoding the .wav from ardour correctly causing the skips in playback through out the track.

I have always used vlc player for everything and have never had problems so it did not even dawn on me to try another play.

The exported .wav files sound very good in audacity.

Again thank you for your response and the hard work you and the Ardour team do.
