Beat Match Analysis

Description

detect tempo and beats in music efficiently

The Beat Match Analysis engine finds the tempo in music. Additionally, it also detects the position of the beats in the music. This is done in a two-phase system allowing you to skip the detection of the location of the beats if you only need the tempo. This beat detection library is designed to work quickly and efficiently with constant tempo music.

User quotes

"AudioStep was using a beat detection mechanism that failed to detect about 30% of popular songs correctly. Once AudioStep was linking to SampleSumo's beat detection library, the error rate came down to 2%. Integration of the library took literally less than an afternoon." - Tibor Horvath, founder Audioforge Labs Inc.

"We've been using your beat-matching library, and we're pretty pleased with its functionality so far" - Matthew Jewkes, co-founder of Twisted Oak Studios, on integration of BMA in their Element Music Player
