Automated Wavetable Synthesizer Testing

Document Thumbnail

This paper describes an automated wavetable synthesizer testing system. Due to the nature of MIDI standards, testing of desired synthesizer behaviour or MIDI standard conformance is not feasible with bit-exact test vectors. Automated testing involves measuring the frequency, timing, and amplitude characteristics of the synthesizer output. Novel signal-analysis based testing methods were developed for measuring the rendering precision of MIDI and instrument articulation parameters. The automated test system consists of a PC host, which controls the test execution, stores the test case parameters, runs the signal analysis, and generates the test report. A modular interface connects the test system to the MIDI synthesizer allowing testing to be done on different hardware platforms using a single set of test cases. Currently, 62 different test groups for SP-MIDI, Mobile DLS and Mobile XMF standard conformance testing has been implemented.
