Samsung DSR synth

The Samsung DSR synth, officially referred to as DSR_###_SAM_## and often nicknamed "the Swift synth", is a software-based synthesizer present on Samsung phones which use Swift system-on-chips (hence the nickname).

It was developed by Eric Laurent at Madwaves, internally known as "Sound Bank for Sy.Sol 6120 SAMSUNG". According to the source file where the name comes from, it has a sampling rate of 32KHz.

The original file format of the DSR synth started out as a DirectMusic Producer DLP file, and can be converted to DLS using Awave Studio among other tools.

The DSR synth was first featured in the Samsung SGH-D600, and earlier Swift phones before it used Yamaha SMAF sound chips.

There are several different versions of the DSR synth, but the differences between them has not been researched thoroughly enough.

As of now, DSR_300_SAM_45 is the earliest known revision of the synth, with DSR_300_SAM_63 being the earliest known revision in a released product, and DSR_256_14 being the latest.

The DSR version can be found by searching for "DSR_" in a .bin or .cla firmware dump of a Swift-powered Samsung phone.
