Is there a portable flac recorder with line-in? tom_a_sparks Light travels faster then sound, which is why some people appear bright, until you hear them speak

Rockbox provides that capability on a bunch of hardware. However, there are some good reasons to not record directly to flac: - the complex format of flac makes audio recovery in the event of a glitch far more difficult than when recording simple pcm/wav - the cpu requirements of realtime encoding require significantly more power consumption, heat and battery drain I have read that the 7xx flac recordings utilize a fairly low level of compression, so the space savings are not that great. Though I have not verified that.

They do quite well at 24-bit/48 kHz, because there was only a 1.3% difference in size between the 7xx FLAC file and the same audio compressed with the flac command-line with --best and --no-padding. In other words, the space savings on 7-Series Sound Devices recorders appears to be about as good as it gets. This is with version 2.65 of the 702 firmware. The actual limitation seems to be sample rate. Although the 7-Series is capable of 192 kHz sampling, it does not allow FLAC encoding at that speed, at least not in stereo. At lower sample rates, such as 96 kHz, there seems to be enough CPU for typical FLAC compression ratios. Brian Willoughby Sound Consulting
