ASIO mutiple clients - What does that mean?

xmos215_167.jpg


ASIO 2.2, multiple clients - Does that mean it is possible to combine e.g. 3 devices and use them as a quasi 6 channel device?

Guys, I can't install driver on win 8.1 pro. It says

"ERROR: Preinstallation of driver blablabla
Installation Failed
Please run setup again"

Help 🙁 ?

Tips:
Thanks for user has the following suggestion for windows 8 driver installation. Problem solved - I was using Windows 8 which needed driver signing to be turned off in order to get the install working. You should note this on your instructions as Win 8 just fails without any message about driver signing!

XMOS DSP filters

Greetings all,

I am interested in an asynchronous interface that will support simple bi-amplification from a pair of DACs. Has anybody tried the XMOS DSP demo code or inserted DSP code into one of these interfaces? http://www.xmos.com/en/download/public/Adding-DSP-to-the-USB-Audio-2.0-L1-Reference-Design(1.0).pdf What XMOS chip would be required to clone and filter a stereo signal as a two-way crossover? Does the DIYin HK chip have enough cores? In my system, 18 dB/octave centered around 150 Hz is good for my separate low freq. drivers. So I would need 4 channels minimum but would also love to be able to obtain un-filtered I2S to supply additional DACs in phase. Anybody doing anything like 4 or 6 channel output from any of these designs?

Any and all comments much appreciated…

Client means: Client Application, while ASIO provides synchronous Input/Output data. Input and output data in one buffer event.

In other words Single Application for input & output or "Multi Client" as sharing the ASIO device with multiple client applications.

Cheers

Please start a new thread on the subject (XMOS crossover) for further discussions. I'm quite positive that all XMOS chips can be used for the task, but we need special hardware with a multi-channel DAC and an ADC or an SPDIF receiver for the input.

We also need the special programming.
This is interesting
YES YES - but I don't want a $ 200 bread board to do this :-(

simply add to cart and press next next finish and download, it's free and do not need to enter any credit card information.
actually, xmos/thesycon require licence fee on each driver copy used, but there are some user uses mac and linux do not need the driver.
we are thinking of a cheaper version without driver bundled.

Thanks Diyinhk, I just have download this driver.

I was doing some testing/listening to high resolution (88.2khz,96khz,192khz) last night and realised that Windows 7 is resampling everything to 44.1khz.

Is anyone here using JRIVER? What settings are you using to get the high resolution files playing?

The new xmos chip is hot!
Digikey is sold out and the next arrived time is 9-17,
I still have few only, may be out of stock again...
Any suggestion for the next version are welcome.
I am planning a more cheaper version with shenzhen oscillator and an expensive version with ndk nz2520sd oscillator

Please add support for multichannel output using TDM (software examples here: https://github.com/xcore/sw_avb/tree/master/module_avb_audio/src/interfaces/tdm and https://github.com/xcore/sw_avb/blo...dio/src/codecs/CS42448/audio_codec_CS42448.xc for codec control ). Now the I2C interface would be nice but I guess that is not possible as the USB driver doesn't support it (it would be nice if you could define the I2C sequence of codec initialization commands in a file in PC - there is though the USB UART interface that could be used for that, right?). I2S input might be useful so that you could route the input from S/PDIF to TDM codec for multichannel audio, or from an ADC and use the XMOS as a DSP for a digital crossover.
