If I have the sound card configured for 32-bit floating point sample size with a sample rate of 96kHz, and the audio player (vlc or ffmpeg for the case) is playing a WAV with the same configuration of the sound card, does the operating system resamples the PCM data?
I'm resampling by myself and I want to percibe the difference, so I need the output to don't be resampled.
I'm using Mac OS.
I resampled by myself an audio file and took a WAV as output, I'm playing with the audio player but I don't know if the OS is doing some modifications on the raw PCM data.
