Hardware: Sony CRX140S CD ReWritable Recorder
Software RH 7.2 kernel 2.4.9-13 sox-12.17.1-4 cdrecord-1.10-4 cdrecord-devel-1.10-4
Using cdrtoaster-1.12 to burn an MP3 to an audio cd results in never recorded before "chipmunks" coaster. The audio sounds like a 33rpm record played at 45rpm. This may be a bad analogy for the CD exposed generation. Analyzing the script from cdrtoaster the creation of a CD takes place in two steps. One step converts the mp3 to wav the next step burns the cd.
Audio convert: mpg123 -s sample1.mp3|sox -t raw -w -s -c 2 -r 44100 - -t wav sample1.wav
CD burn: cdrecord -v -eject dev=/dev/sg0 speed=4 -audio -pad /home/username/sample1.wav
I have tried doing the audio convert manually an it produces a chipmunks wav file. If I change the rate parameter to -r 22050 the wav file is produced correctly. The new file is not in the correct format for cdrecord to handle and produces an error message "Inappropiate audio coding". According to my reading a wav file must be created with 16bit 44100hz sample rate. I have also tried changing the mp3 player to the GPL version mpg321-0.1.5-1 with no success. I have found no indication at the SOX site of any problems with the software.
This is my first foray into CD burning using Linux. The burner works fine under windows95 and its software. I have made a decision to eliminate as many windows machines as I can. My project is the burner/scanner box.
