holy crap!
« on: May 15, 2008, 01:23:53 AM »
I just decided to try this on a whim, as NiN's latest album (the Slip) can be downloaded in 24bit, 96000 wav if you want (and I did...) (and it's free, if you haven't heard)

I encoded these WAV files to FLAC, leaving the sample/bitrate untouched, tagged it, replaygained it, added album art... and rockbox plays it WITHOUT ISSUE.

It takes a while to fill the buffers, and I have cut my max playlist size to 2k and max directory size to 200... but I'm still VERY impressed. I'm not sure if those measures were required, but I don't need them any higher anyways. When you can play audio at over twice the Nyquist... just wow. That's on a portable player.

Question though: On a Sansa e200, do we know what actually comes out of the hardware once rockbox is done with it?

EDIT: Whoops, about halfway through the song something Bad happened - the playback thread just stopped, buffers quenched, but memory still allocated. I had to hard-shutdown (hold the button a long time) - this has happened to me occasionally anyways, not sure if it's isolated.

Rockbox currently resamples everything to 44.1khz 16-bit for analog output on software codec targets (for example, the Sansa).

Yea, I figured that out on IRC. Apparently it's a fast but lower quality resampler?

Strangely enough, even after knowing that, I could swear the higher-resolution on still sounded better - even though it should have been worse, if anything!

But... following logic, i dropped the 96,000/24 to 44100/16 with a good resample and just stuck that on the player.

At least you save some space that way.
