SPH to TXW Converter

TXW is the native audio sample format of the Yamaha TX16W, a rack-mounted digital sampler released by Yamaha in 1988. Each TXW file stores a single audio sample captured by the TX16W's 12-bit analog-to-digital converters, with selectable sampling rates of 16.7 kHz, 33.3 kHz, and 50 kHz in mono. The format was engineered to work within the sampler's architecture — 1.5 MB of onboard RAM expandable via memory cards — so files are compact and structured for quick loading from 3.5-inch floppy disks. Despite its 12-bit resolution, the TX16W earned a loyal following among electronic musicians who prized its distinctive warm, slightly gritty character that imparted a recognizable sonic texture to sampled material. The format preserves loop point data and tuning metadata, enabling seamless playback of sustain loops within the hardware. While TXW files are not directly playable in most modern software, conversion utilities and the SoX audio toolkit can transform them into contemporary formats like WAV or AIFF. For vintage synth enthusiasts and sample library curators, TXW remains an important archival format.
