Converting from .FLAC to WAV increases bit rate

Appreciate the feedback.  The only benefit to converting FLAC to WAV might be to get the same quality onto an IPOD for docking to a Wadia iTransport or the like.

Normally when a CD is converted to FLAC it has a (variable) bit rate around 600 kbs.
CD= 16 bit / 44.1 kHz in WAV has a fixed bit rate of 1411 Kbit/s.
File size is reduced by approximately 40%
If you see a 10 fold you have probably done something more than plain converting like changing the bit depth to 24 bit and/or increasing the sample rate.

The bit rate of MP3 files does relate to audio quality.  The bit rate for Flac files or another lossless format like APE or ALAC is not an indication of audio quality.  After the Flac file is unpacked, the amount of data going to the audio output device will be same as for the corresponding WAV file.

The factor of 10 you saw is unusual.  A ratio of 1.5 to 3 is more normal.

By the way, did you realize that JRiver MC can convert files from one format to another?

The huge destructive downside to this conversion is the instant destruction of your metadata tags as wav files are useless for storing any sort of meaningful tag data.

As many of mentioned - FLAC is where it's at. There is no reason at all to ever decompress them - especially if MC is handling audio playback for you.

If you want the same quality for the Wadia etc...convert FLAC to Apple lossless and preserve your tag data and your sanity :)
