What is a .YM file?
YM holds chiptune music from the Atari ST’s YM2149 sound chip.
- Did you know
- YM captures the distinctive sound of the Atari ST’s music chip.
- YM was devised by Arnaud Carré (“Leonard”) for his ST-Sound emulator, and the file is really a register dump of the chip replayed cycle by cycle.
- The same YM2149 sound chip powered the Amstrad CPC, the ZX Spectrum 128 and MSX machines, so YM can capture tunes from across the 8-bit and 16-bit era.
- What Analyser reads
- Identify many more audio formats: lossless/hi-res codecs (Monkey’s Audio, WavPack, TAK, True Audio, DSD/SACD, Musepack), pro containers (Core Audio, RF64/BW64, Wave64, Sun AU, Broadcast Wave with timecode), speech/mobile (Speex, AMR-WB, QCP, 3GA, M4R, GSM), MPEG Layer I/II, instrument banks (SoundFont, SFZ, DLS, RIFF MIDI, GigaStudio), ringtones (RTTTL, iMelody, SAP), tracker modules (MOD, XM, IT, S3M, OctaMED, 669, Oktalyzer), chiptunes (NES NSF, SNES SPC, VGM, Game Boy GBS, AY, YM) and Audacity projects.
- Depth of analysis
- .YM is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .YM file
- Drag a .YM file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
