My name's Álvaro, from Barcelona [it's my first post to this list, so I say
hello :) ]. I'm dealing with some issues with time-scaling and I'm a little
bit lost trying to find the problem.
I'm trying to record an analog audio input using *arecord*, in order to do
some fingerprinting (features extraction). The problem is that after every
reboot of the recording machine, the record has a different time scale so,
as the fingerprint algorithm works with the relative position of energy
peaks for different frequencies and the time them happen, the algorithm
sometimes works, but sometimes fails.
Could you give me any guidance to know where to search a possible solution
for the time-scaling issue? Thank you very much in advance!
Forza saluti a tutti bacioni auguri in boca di lupo arrivederci ea presto
