Subject: Re: [AUDITORY] High fidelity cocktail party recordings From: Jonathan Le Roux <Jonathan.Le-Roux@xxxxxxxx> Date: Sat, 12 Sep 2020 11:57:34 -0400--000000000000243e4205af1fdde6 Content-Type: multipart/alternative; boundary="000000000000243e4105af1fdde5" --000000000000243e4105af1fdde5 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Hi Brian, You may be interested in the noise we used to build WHAM!, a noisy speech separation dataset: http://wham.whisper.ai/ From the website: "The noise audio was collected at various urban locations throughout the San Francisco Bay Area in late 2018. The environments primarily consist of restaurants, cafes, bars, and parks. Audio was recorded using an Apogee Sennheiser binaural microphone on a tripod between 1.0 and 1.5 meters off the ground." The (currently) publicly available data is only at 16 kHz: "The clips are in 32-bit floating point WAV format with 2 channels and a sampling rate of 16 kHz." (the precision is actually 24 bit, despite the encoding being 32-bit) But your email as well as a couple other requests we recently received for higher sampling rates convinced Whisper.ai and us to make a separate release of 48 kHz noise data. This won't simply be a 48 kHz version of the short files that we released for WHAM!, but instead a collection of longer recordings of various lengths, obtained by cutting the original data every time we determine there is somewhat intelligible speech in it. This should provide the maximum amount of data to researchers interested in cocktail party noise. We are currently preparing the release, and will announce it on this list when it is ready, hopefully within a few weeks.
