Audio Compression

My own little test...

The 8,000Hz sample was kind of quiet but other than that it was difficult to tell the difference of the quality of sound in the different samples.

Recording a 3 second audio track at the following sample rates gave me these results:

• 8,000Hz - 39.4KB
• 11,025Hz - 43.3KB
• 16,000Hz - 46.1KB
• 22,050Hz - 51.0KB
• 44,100Hz - 48.5KB (Same sampling rate as uncompressed CD audio)
• 48,000Hz - 44.3KB
• 96,000HZ - 26 bytes (something obviously went wrong here, was unable to open and listen to track.
