HiRes Binaural+ with ALSA

Binaural recording is a method of recording sound that uses two microphones, arranged with the intent to create a 3D stereo sound sensation for the listener of actually being in the room with the performers or instruments.

192kHz · 24bit

Minimal HW requirements:

1. Computer with Intel HDA codec on motherboard.
NOTE: Very old computers (e.g. of 2006) may not have Intel codecs which support 32bit 192kHz.

2. A cheap analog headset (e.g. Sennheiser PC 3 Chat), or headphones.
NOTE: USB and wireless headsets are not suitable for the purpose.

Software: ALSA, fftrate ALSA plugin, Audacious.

Audacious → Settings → Audio → ALSA Output 32bit

To prevent resampling, configure fftrate for 32bit 192kHz (although, of course, 99.99% of Linux users may hear the difference, if resampling was made by Petrov's fftrate)

There is a belief that Petrov's fftrate may cure deafness, but it may not help PulseAudio users.
