"The Monster Mash", 8 to 1 ADPCM compressed sample playing through the Quazar Surround soundcard (my first #hardware release back in 1995 for the SAM, 2024 edition available: www.samcoupe.com). #Z80 ADCPM sample routines coded in 1997. ~490K = 3 minutes!

Tis that time of year to rake out the Halloween CDi from my BGM Days
3 Hour CDi of Halloween (ish) tunes - about 2003
Philips BMS 3000 CDi Audio Player
Disc - Level B - Green Book - Mono - ADPCM - 37.6 KHz
I seem to remember this was initially produced for McDonalds

ok wip 2. i moved to y8950 for that lovely adpcm-b channel 🥰 otherwise, it's the exact same as OPL1.
more complete and stuff too Yay

とりあえず自作は全部ADPCM音源に差し替えるとして譜面の方でどう対策するかだなぁ

So, not the buffer, not the ADPCM code.
I didn't analyze the SWAVs for BW/B2W2 yet; not sure that may yield a clue, however.

"Palettes cycle and patterns flash as the PCM sound channel receives instructions, and in mutual exchange, the PCM channel plays chunks of compressed ADPCM audio as uncompressed PCM and even dips into some of the code surrounding those memory addresses, conjuring up deafening blasts of static."

audio editing SOMEHOW the most nightmarish of it all. for all ima adpcm files it allocates fixed amounts of memory, new samples cannot be bigger than the old ones. depending on what you edit the max sizes are 8323, 16671 or 33367

elaborate:
(the Microsoft ADPCM codec is used for Xbox, Xbox 360 and GameCube games btw + ignore the static, I used Audacity instead of FFmpeg to export the audio)

I'm this close to buying two more PicoGUSes, thanks to the new functionality!!
Question though, is ADPCM still on the backlog?

After two weeks of programming, my sequenced music finally works on PS1.
Previously, I could only play existing PS1 tracks from other games from .SEQ/.VAB/ADPCM files.
Making my own tracker format + properly encoding samples was incredibly complex, but I did it!

hell i wouldn't mind one either, adpcm-b gets a little heavy

The Scheme by Koshiro & "God" deliver prog-rock energy, full FM plus ADPCM usage with some melodic samples, and strong bass work. It squeezes nearly everything out of the OPNA chip - minus PSG. Star Cruiser offers a complex sci-fi fusion OST, only lacking in advanced ADPCM, and PSG use.

I implemented my own VOX ADPCM (https://en.wikipedia.org/wiki/Dialogic_ADPCM) encoder and decoder in Rust! The purpose is to apply the sound quality of a codec to a sample—in this case, it's a 4-bit telecommunications algorithm that sounds fizzy and crackly

TurboGrafx-CD debuts in late 1988, and with it, sampled ADPCM speech/drums arrive (although rarely used). PSG often remains for various BGM in the CD games, but the bulk of the music is CD redbook audio.

Almost finished integrating the Fusion Driver by Vic into SGDK! This will let SGDK devs fully utilise the Sega Mega CD's sound hardware using ADPCM samples, SPCM, and CDDA. Exciting times for #SegaCD #MegaDrive #Genesis #SGDK #IndieGameDev! 🎵🚀

This 1986 SNK arcade game had the incredible technical flex of a song with full vocals, using a special ADPCM chip. The slapdash EN localization simultaneously ruined it & made it oddly evocative—

the easier thing to do though would be to figure out what adpcm is and to try to make a converter myself instead of using audacity because I feel like audacity messes the audio up a bit(?)

疑問点
* 可逆圧縮とaptX非可逆圧縮（ADPCM）を聴感上の違和感なく行き来できるのかどうか。
* 1.1Mbpsの帯域幅と可逆圧縮を使用できない状態になったときに、AndroidやBluetoothデバイスが「Lossless」と表示し続けるのか、「Adaptive」と表示するのか。

Well, it would probably be streamed ADPCM tbh. With CD audio I would not be able to load data off of the disc while the song is running - sure hope you like the song restarting every time you walk through a door!
(streamed ADPCM would be its own headache, ofc, wrt loading other data simultaneously)
