Changelog

0.10.1

• Pulling the headphones out pauses.
• Infinite shuffle.
• Fast scrolling in big folders (EXPERIMENTAL):

0.10.0

• Equaliser: ten bands from a 31 Hz low shelf to a 16 kHz high shelf, ±12 dB each, at every rate and depth, gapless, edited while the music plays, with automatic headroom. Settings → Equalizer opens the bands; menu there turns it on and off.
• ReplayGain: track, album, or auto (album in order, track in shuffle), with a preamp, a gain for untagged files and clipping prevention from the tags’ peaks. The finer knobs are in RECHO.CFG.
• Both are off by default, and then not one sample is touched.
• Spectrum: a scrolling 70-band per channel waterfall of what’s playing, a page of the main menu.
• A redesigned play screen.
• Lifted the queue limit. The 400-track cap is gone.
• Resume at power-on: the menu (the default), the file browser or the last track, paused where it was (this will be a favourite of audiobook listeners).
• Pocket controls: with the screen off, hold play for the next track and back for the previous one.
• Play a whole volume: hold play on Internal or SD card.
• Battery: the bars show the charge; a low battery warns, then powers off cleanly.
• New settings: Clock, Swap up/down, Power on (instant or hold to boot).
• Smoother and faster: hardware accelerated rendering wherever it’s possible. 100ms boot.
• Fixes: no click when skipping tracks; powering off on the cable stays off, dozens of smaller bug fixes and QoL improvements.

The EQ and RG marks explained

• EQ is lit, with its curve beside it, when the equaliser is on.
• RG is lit, followed by the gain you hear, when ReplayGain is on.
• The small letter in the RG chip says where the gain came from: T the track’s tag, A the album’s, X no tag on the file (the untagged gain). A second A on top means the mode is auto.

The preamp (−12…+12 dB), the untagged gain (−12…0 dB) and clipping prevention (on by default: the gain is held so the tagged peak stays below full scale) are set in RECHO.CFG; the total is kept between −30 and +12 dB. Settings → Gain change picks a 10 ms ramp (default) or a step between tracks.

0.9.2

• About page: and a big THANK YOU to supporters.

0.9.1

• Tags wherever the file keeps them. Besides the tags at the start of a file, 0.9.1 also reads the ones at the end: APEv2, an appended ID3v2, ID3v1, and WAV tags after the audio. When a file has more than one tag, the first one found wins, field by field.
• Tags are read apart from playback, asynchronously on the system core.
• New setting: Show tags. It’s on by default. Turn it off and the player reads no tags at all: the play screen shows the file name and folder, as before 0.9.0.

0.9.0

• Tags: title, artist, album and track number. Read from ID3v2.2–2.4 (MP3, and WAV’s id3 chunk), FLAC’s Vorbis comments and WAV’s RIFF INFO. Covers, lyrics and padding are skipped, never loaded. A file without a title tag shows its name and path.

0.8.1

• MP3. CBR, VBR and ABR; MPEG-1, 2 and 2.5, 8 to 48 kHz, every stereo mode. Gapless too, when the encoder left a LAME header (LAME does), the same way mpg123 or foobar2000 do it.
• Enabled the microSD card. Browse and play straight from the card, FAT32 or exFAT. The card is mounted read-only. The second USB LUN is intentionally not implemented, so you can’t use the player as a card reader, and there are no plans to add it. Use a dedicated card reader to manage the library.
• Big cover art doesn’t break playback anymore. In 0.7.0 a FLAC with a 531 KB cover never started (thanks to the redditor who sent theirs). Now files stuffed with megabytes of covers, lyrics and tags play, and stay gapless across them; the gapless test set has a stuffed set to prove it.

0.7.0

The first public release, with not one line of Snowsky’s code. FLAC and WAV up to 192 kHz / 24 bit, decoded on the second core with its hardware accelerator for FLAC. Gapless! Folders and files sorted by name, and hold play to queue a whole folder. Volume in 1 dB steps. Play modes, resume, settings in a text file. Installs and uninstalls through the stock updater.
