PS: I take advantage of my first post to greet GS, and give big thanks to the GS community. This would be a correct solution to me if confirmed. Some people advise to not use any USB/Firewire/PCI streaming interface as it alters bit-perfect recording: Just use audio interfaces writing to an internal disk or SD card, and then access the files via USB/Firewire/Card reader (like Tascam HD-P2). It seemed to me that when the input signal flew directly to the USB/Firewire/PCI interface without extra processors, I would get a bit-perfect recording. Some gears' manuals indicate their internal signal flow. Is this just marketing effect, or do I have to conclude that other gears will get a hard time in having bit-perfect recording ? Some gears have special features to ensure bit-perfect recording: Creative has bit-accuracy mode but works only up to 96khz, and Weiss DAC202 has transparency check but is over budget for me. Here are some experiences I have gathered around: Here are some of the interfaces I have considered so far:Īnd tons of others (I can post my entire research if some are interested: 67 audio interfaces). So I have a few questions regarding this issue:ġ- What parts of the signal flow (from the PCM stream to the file) might alter the audio data ? Drivers (ASIO, WDM.) ? USB/Firewire/PCI/PCIe protocols ? Audio interface internals ? Recording software ? OS ? What have you experienced and pointed out as problems ?Ģ- What would you advise me to consider buying ? I would have thought that any interface would be ok as long as no A/D or D/A conversion altered the flow, but after googling and searching around GS, it seems that people can't get an exact bit-perfect recording of their source (failing null tests with just digital loop-backs). I have found many audio interfaces that would fit the specs, but can't find any guarantee about the bit-perfect feature. I don't care about latency (as long as I don't have dropouts). I want to record this stream in my PC with bit-perfect accuracy (getting a WAV, FLAC, RAW file). I have a digital stereo PCM stream out of AES/EBU (or S/PDIF) from my converter (24bits/192khz single-wire).
