Detailed Description

A collection of functions which simplify transcription (detecting onsets via pitch and amplitudes, calculating notes, etc).

Member Function Documentation

mrs_real findMedianWithoutZeros	(	const mrs_natural	start,
		const mrs_natural	length,
		const realvec &	array
	)			[static]

non-Transcriber-specific functions, but I don't think they're useful enough to add to realvec.

Definition at line 24 of file Transcriber.cpp.

References realvec::create(), realvec::median(), and realvec::stretch().
