Ripped stereo ac3 audio track from DVD. Edited within Audacity (audio multitrack sequencer for linux) and then exported as standard 44.1 khz audio stereo.
Within audacity, final edit sounds amazing, wonderful.
Import to the blender sequencer via the ‘add>audio’ command.
The sound is rather unusable, full of audio aliasing, no stereo pan almost, no depth, no nothing.
I have also tried the same task but with no resampling in audacity at all. That is, I managed to get Blender import original 48 khz stereo audio track. In any case the final result is just the same.
hey… I’m away from my computer right now so I’ll try to copy it when I get there… but try a different bitrate… maybe lower?? Not a noob… just joined the forum… my backgrounds audio work… try to get back to you on that one
–It is uncompressed wav audio file, and tried at both CD sampling frequency (@44.1 khz) as well as DVD sampling frequency (@48 khz), which according to the manual, Blender is intended to support. The result of the import were in both cases unacceptable, full of audio aliasing.

okay… here goes… first I ripped a track from a cd (mp3)… I then used Goldwave to open up the song a take a slice from it… i then saved the selection as a 16bit wav file… I opened up the sequencer and dropped the audio file on the timeline… pressed play… it worked like a charm!!! Perfect audio quality! :o sooo… is it the system specs? I’m running a 750mhz AMD Duron with 128 mb of memory… YEah… sooooo… here’s a couple screenshots of the wave file stuff… (i’ll try 24bit audio next) ohhh… ANOTHER THING!! What version of Blender are you running? I’m running 2.40…
a) Blender will not support any audio bitdepth other that 16.
b) Check that your `real’ audio sampling rate matches what is selected in the Sequencer>Audio-sequencer settings sub-context buttons, in the audio buttons (you get there by pressing the icon with the waveform). These only can be 44,1 or 48 khz. Thus, if you use any other sample rate, chances are you will be prone to audio aliasing.
c) Don’t forget to click on `recalc’
This solved the problem, audio aliasing is now gone.
So I stay tuned.
