Speed¶

Test hardware and material¶

Thinkpad T540p, 2-core+HT 64-bit Intel i5-4330M under 64-bit Linux.

Input file is a 21 min 27.76 sec 16-bit 2-channel WAV file. All timings carried out by running the Vamp plugins under Sonic Annotator v1.0 and sending the output via the CSV writer to /dev/null.

Reference¶

Note: CQVamp produces a much higher time resolution output than the QM Vamp Plugins implementation, so it's not unreasonable for it to be a bit slower (though it'd be nice if it weren't).
