5 Audio CD: horrible quality - ID: 2687042
Last Update: Comment added ( maartenapple )

When trying to burn an audio CD from a 15 minute wav file, the result is
many glitches/skips and the last few seconds of the audio are not present
on the CD.

Tried multiple times with different media and CD players.

When burning the same wav file with iTunes, there is no problem.

Seemed to be a problem in Apples DiscBurning.framework. Should be fixed in
Burn 2.3u, since it now uses ffmpeg for creating Audio-CD tracks.

Follow on from previous comment and solution to stutter. On reexamination
of the WAV files used in creating the two AudioCDs with stutter, confirmed
that one set were all 16 bit while the other set for the second Audio CD
were a mix of either 16 bit or 32 bit (don't ask). All the WAV files in 32
bit format burn OK and without stutter; the problem only occurs with 16 bit
WAV files. Saving 16 bit files in 32 bit format and then burning them works
fine and there is no stutter. So, the answer is: record WAV files in 32 bit
format for stutter free Audio CDs.

As for the previous users, burning WAV files as Audio CD results in
stutters during playback. WAV files generated using Sound Studio. First few
burns with WAV files processed with Sound Studio were flawless. The last
two sets of files burnt as Audio CDs had stutters. Both these sets of files
however were successfully burnt using iTunes or ExpressBurn. One of these
sets of WAV files was in 32 bit floating format, 44,100 sampling rate; the
other was as 16 bit. Earlier sets of WAV files successfully burnt to Audio
CD were all 32 bit floating format. Earlier WAV files which had been
successfully recorded could still be burnt successfully so I don't think it
is a CD writer or media problem. Tried saving WAV file with Audacity but
still played back with stutter. Great interface to Burn and so easy to use;
good if this problem could be fixed.

I have the same problem. Audio CD burnt from wav files sound with glitches
around every second or so. Last second or two is cut from every track. Also
sounds like each track starts playing maybe half a second before it should
(ie just before the end of the 2 second track gap).

I have two CD writers: OPTIARC DVD RW AD-7170A & SONY DVD RW DRU-840A.
Tried both - same problem.

The wav files were generated from VLC 0.9.9a via audio transcoding and the
wav codec was set to uncompressed *integer*.

I get the same symptoms. I noticed that this started when I upgraded my OS
from 10.4.11 to 10.5.6. I was running Burn verison 1.71u at the time, so I
upgraded to version 2.2u, but still had the same problem.

I tried burning the same wav files with Amadeus, and they sound fine.
