![]() Select Tools > Options > Audio > Bitstreaming and select DSD.You must have your Audio Output Mode set to WASAPI Event Style, ASIO, or Core Audio.DSD over PCM requires Media Center 17.0.106 or newer. JRiver was part of the formation of the DoP standard. This is not a conversion to PCM, but a native DSD signal packed into a PCM container. (In earlier versions, Bitstreaming is under Tools > Options > Video instead and you may need to select Custom and choose DSD).ĭSD over PCM packs DSD into a PCM-like signal for bitstreaming. Select ASIO as your Audio Output Mode in Options > Audio > Audio Device.The ASIO driver for your DAC must support it. This uses the native DSD bitstreaming support built into ASIO 2.2. There are multiple DSD bitstreaming technologies: With a DAC that supports native DSD playback, it is possible to bitstream DSD and bypass MC's audio engine (and, therefore, the DSD to PCM conversion). There's a little more detail on our default low-pass in this ComputerAudiophile thread. It is not recommended to change the filter from the default, since the other options will not completely remove all ultrasonic noise from the output. The low-pass filter can be selected via Tools > Options > Audio > Advanced > Configure input plug-in > JRiver DSD Plugin. ![]() The default low-pass filter is at 24kHz using a 48dB/octave slope. Therefore, a low-pass filter is used to remove this ultrasonic noise at playback time. To enable downsampling, set '352,800 Hz' (1×DSD) or 'Greater than 384,000 Hz' (2×DSD) in Player > DSP Studio > Output Format to the highest sample rate supported by your hardware.Īll DSD rates higher than 1× are handled by the 'Greater than 384,000 Hz' setting.ĭSD contains high frequency noise that could potentially degrade sound quality or even damage equipment. ![]() Not all hardware devices support these high sample rates, so downsampling is normally required. Once you have PCM, it will be 64bit 352.8 kHz for DSD, and 64bit 705.6 kHz for 2×DSD. The total amount of data from this conversion grows by 8x, so the process is effectively lossless / perfect. The DSD to PCM conversion process converts from 1-bit DSD to 64-bit PCM at 1/8th of the DSD sample rate. By default, DSD sources will be converted to PCM for playback and handled by the Media Center audio engine like any other file type.
