Question about C program source code #61

Open bk1412 opened 1 year ago

bk1412 commented 1 year ago

When I used the loudness_zwtv function to analyze some audio, I found that its running speed was very slow. The same is true for the roughness_dw function. I learned from the comments of the loudness_zwtv function that the mosqito project seems to have the source code of the C program version. Someone can provide it What, I want to improve the speed of operation by using the C program version of the function

there is the comments

"""Calculate Zwicker-loudness for time-varying signals Calculate the acoustic loudness according to Zwicker method for time-varying signals. Normatice reference: DIN 45631/A1:2010 ISO 532-1:2017 (method 2) The code is based on C program source code published alongside with ISO 532-1 standard.

The place to find software routines associated with standardised signal processing methods is https://standards.iso.org/iso/. For example, look in there for the 532 folder, and within each subfolder, a software tool (either C or Matlab depending on the corresponding part of the ISO) is provided.
