List WAV file attributes without audioread

2 次查看(过去 30 天)
Hi all,
I have a large data set of wav files (each file is sampled at 500kHz on 4 channels) and I need to create a table with the filename and duration (as well as some other data which is extracted fromt he file name). I am able to do this with audio read but it takes such a long time to load in each file. Is there anyway to extract the file name and duration from windows explore for example? Or are there any other functions that could do this without loading in everyfile like audioread does? Or even any way of speeding up audio read, for example only loading in one channel rather than all four?
Thanks in advance! :)
Thomas

just remembered that there is a better way ! just do this inside a loop and you're done
info = audioinfo(filename)
info =
struct with fields:
Filename: 'C:\Temp\handel.wav'
CompressionMethod: 'Uncompressed'
NumChannels: 1
SampleRate: 8192
TotalSamples: 73113
Duration: 8.9249
