External soundcard using TI's PCM 4202 converter?

    Hi :)

    I'm trying to find a soundcard that uses Texas Instruments PCM 4202 A/D converter. Korg makes the MR-1000, 2000 & MR-2 but I'd prefer to find something less costly. Any of you know if this exists?

    Greetings,

    Jesper

    P.S.: I'm also interested in an SPDIF/AES to USB/firewire "converter" or "unit" so that I may connect a 192 kHz/24 bit SPDIF/AES output from an AD converter to a PC. The USB/firewire unit should have drivers & software so that it can record from the AD converter to the PC. This also is a very attractive option to me so any insights on this really are appreciated!

    It looks like the MR1000 is DSD based and not PCM in which case you will be hard pressed to find anything similar. DSD just isn't a popular format. Most of the companies trying to use it have moved on. Also, it's highly unlikely that you will find a lower priced unit than the ones from Korg. If you do consider a DSD based unit that is still supported, it will likely run you well into the thousands of dollars. Even then, you're going to spend thousands more on software that supports DSD. I don't know of any.

    I seem to remember some of your other posts about 192kHz being too low a samplerate. Anyway...........

    Hi Hueseph,

    Thanks again for replying - have a vague recollection of you also replying to some of my previous posts which were about higher sampling rate "systems"... ;-)

    And, yes, DSD seems to not be a very supported format on the technical side, although I notice that some bigger record companies still issue SACDs, like e.g. Harmonia Mundi and Sony. There apparently is also a good collection of SACDs available according to sa-cd.net.

    Anyway ... I'm also interested in finding an SPDIF or AES/EBU to firewire or USB converter (including win7 drivers & software) so that I can record to a PC with an outside ADC having SPDIF or AES/EBU outputs (192 kHz/24 bits). So if one of you knows of this I'd appreciate hearing about it.


    Best regards,

    Jesper

    Hopefully without sounding unserious in this then as low as possible for a soundcard solution, yet with a reasonable sound quality. I'll be modifying it anyway so re-sale possibilities will be low and I most likely will just use it for a shorter period of time.

    For an spdif/AES-EBU to USB or firewire converter + software solution it depends on the options, e.g. can I change the clock circuitry & modify other parts so that it is more "future-proof" for me. And will the software allow me to record close to on the fly.

    Hope it makes it just a little clearer - it's not price as such but the extent to which I can use it now, and/or in the future and also modify it with some ease. And, then, as you noted above I don't find that 192 kHz is a sufficient sampling frequency for my purposes so paying a lot (probably more than USD 400) is no that attractive to me. Hope it makes it clearer ...?

    Best regards,

    Jesper

    Hi Hueseph,

    I might have found a solution(s). Either of these looks like where I'm heading so I'll just pause this thread for now ...:

    Open-source USB interface: Audio Widget - diyAudio

    XMOS-based Asynchronous USB to I2S interface - diyAudio

    Best regards,

    Jesper
