Filtered audio data are divided into windows of samples (whose dimension is the sample frequency, i.e. 1s). A peak detection algorithm is applied to each window and identifies as peaks all values above a certain threshold (defined as C ⋅ a v g ( w i n d o w) where C is for the user to be configured, e.g. 0.95 ).

Grumpy_Mike August 16, 2012, 9:50pm #6. The problem with using an FFT for beat detection is that you have to sample for long enough to actually get some beats in the FFT window. This pushes up the memory requirements and thus the processing requirements, unless you have a fairly heave low pass filter on the front end.

to the BPM. A Fourier Analysis-based BPM detection algorithm, developed by Eric Scheirer (Tempo and beat analysis of acoustical musical signals) i. was adopted and implemented. In contrast to other popular algorithms, the main advantage of Scheirer’s algorithm is it has no prerequisite to decompose the audio information

We can choose a linear decrease of 'C' with 'V' (the variance) and for example when V 200, C -> 1.0 and when V -> 25, C -> 1.45 (R5). This is our new version of the sound energy beat detection algorithm: Simple sound energy algorithm #3: Every 1024 samples:

Ideally, the algorithm would have a parameter to adjust sensitivity to beat event detection. That way, the sensitivity could be automatically increased to make sure events are detected even in bad conditions (low music volume, noise from conversations, etc.) My questions are thus: What (class of) algorithm would fit appropriately this application?
