![]() ![]() Amanero updated the firmware and released ASIO drivers.įor instructions on enabling native ASIO playback, you can follow this excellent post:Īmanero ASIO or you can get the ASIO drivers from the Amenero site. Recall that previously ASIO4ALL was used because the Amanero lacked native ASIO support. The latest foo_dsd_asio plug-in handles all sample rates as shown in the following results: To install or update foo_dsd_asio, run the ASIOProxyInstall-0.6.x.exe program. Thus, foo_dsd_asio has the following functionality: The Amanero board handles “ASIO native”, but other boards may require a marker on the DSD stream. On the PC side, there is no native support for USB2 audio so people use ASIO and ASIO can support both PCM and DSD streams. This “marker” method is predominantly driven by the MacOS since its built-in USB2 audio driver only supports PCM. Marker 0×05/0xFA means use the marker (for DSD) as specified in the proposed “USB Link for DSD Audio via PCM Frames” open standard. (Actually, ASIO itself is a meta-device driver because it talks to the actual device driver)įor one thing, foo_dsd_asio handles the “DSD playback method”: for example, “DoP Marker 0×05/0xFA”. Apparently the sacd plugin does not output directly to an ASIO driver, it must go through the meta-asio driver. It is used by the sacd plug-in above as the output device and in turn foo_dsd_asio outputs to an ASIO driver for an actual device. The results were as expected: PCM Conversionįoo_dsd_asio is kind of a “meta-asio” driver. I tested the conversion of DSD to PCM, using both DSD64 and DSD128 files. The control panel looks like this: you can select DSD output or PCM output (when converting DSD to PCM) To install or update foo_input_sacd, just drag it to the components window in foobar and click “apply”
