The SPL sample file format was introduced along with Digitrakker.

THE SAMPLE-FORMAT (SPL)


SPL, was used in older tracker-versions (V2.0-V2.2). This format isn't supported any longer in Digitrakker, that means you can read it, but you can't save samples in this form. The reason for this step was the fact, that there are too many sample-formats and it makes no sense to introduce a new one, because the existing IFF-format nearly contains all infos you need for a Digitrakker-sample.


Offset Length Description


000 004 "DSPL"; the four letters mark the spl-format

004 001 version; the current version is 0

005 032 sample-name; the name of the sample (filled with [32])

037 008 filename of the sample

045 002 C-4 sample-frequency in hz (00000-65535)

047 004 sample-length

051 004 sample-repeatstart

055 004 sample-repeatlength; if this value is set to 0, the sample will not loop

059 001 sample-volume (1-255)

060 001 infobyte:

bit 0 -> 0=8 bit sample, 1=16 bit sample

bit 1 -> 0=forward looping, 1=bidirectional looping

bit 2,3 -> packmethode (0=not packed, methodes 2 and 3 doesn't exist in this version)

bit 4-7 -> not used (should be set to 0)

061  ??? sampledatas... (see above)
