[linux-audio-dev] [ANN] Audioscience Driver version 300 released
Greetings, Version 300 of Audioscience HPI driver has been released and can be downloaded from here: http://www.audioscience.com/internet/download/linux_drivers.htm There are many changes, please read the release notes for details: http://www.audioscience.com/internet/download/drvnotes.txt In addition ALSA has been updated to use the same source code and DSP files. Currently only available in the ALSA Mercurial repository: http://alsa-project.org/download.php If you have any problems or queries about this new driver, please email support@ (our domain name), include info about your distro, kernel version, card type etc. regards -- Eliot Blennerhassett AudioScience Inc

FYI AudioScience has put a lot of effort into making linux drivers, firstly our own HPI API, then ALSA. This is ongoing. Driver is released under GPL, users libs under BSD style licence. We could always do with more help from the community though ;-) http://audioscience.com/internet/download/linux_drivers.htm regards Eliot Blennerhassett AudioScience Inc.
Re: Behringer [was Re: [linux-audio-user] Re: [linux-audio-dev] RME is no more]
Ah i don't know. I mean, you guys have put a lot of time into what your doing anyway. And in my case the trust in rme turned out to be a bummer just becasue i was thinking that they have trust in the open source developers. If they did have such trust, something like this would never happen. Once again, the simple answer is www.audioscience.com. Why don't the guys who do the driver development see if audioscience Thanks for the vote of confidence! Do you mean the ALSA developers? Audioscience does its drivers for ALSA, no volunteers needed. :) Not so fast... we at audioscience would love to have some help with our ALSA driver and our underlying HPI driver. We are a small company that supports various Micros~1 flavours as well as Linux 2.4 and 2.6 kernel variations. I am the single person who does all the linux stuff, and would still say I don't know enough to do it easily or properly. (Of course I have had help from our customers and other alsa developers, and kudos to Takashi Iwai for doing the work to incorporate our ALSA driver into the alsa tree) So step right up... would be interested in producing pro audio cards (not just broadcast) with driver help from the OS community. They seem like they have their act together. So, what is the difference between our current offerings and what you'd like to see in a pro audio card? Seems like a good idea to me. The 5044 cards offers 8 analog i/os of 24/192 and i wonder whether such card could not already be used for studio purposes. But in any case, they're very close. Marek regards Eliot Blennerhassett
[linux-audio-dev] [ANN] AudioScience HPK version 2.88 released
See the release notes and get the tarball from here http://www.audioscience.com/internet/download/linux.htm Many updates to specific card features, plus support for Linux kernel 2.6.x. Also on the same page can be found the patch for alsa 1.0.5a (I know, I'm lagging behind) regards Eliot Blennerhassett AudioScience Inc.

I tend to look at it (very conveniently, of course) as neither. I view it as part of the hardware device we're dealing with. Without it the device does not work. It is distributed as a separate file (inside the driver disk that actually comes with the device) because it is convenient for the manufacturer for updates, avoiding a flash rom in the device, and so on and so forth. Replying as an audiocard manufacturer (www.audioscience.com), this is exactly true for us. We have one external box (ASI2200) that can theoretically run standalone from internal flash, but for convenience of update, the firmware is downloaded by the driver every time. Firmware is supplied as a binary data file. As our linux driver is open source, the means of loading the data is there for all to see. All the code that runs on the host computer is open under either GPL or BSD style licence. But there is no way the company would release the source code for the firmware! (in fact we are contractually prevented from doing so in some cases). Most probably very few people will agree with this viewpoint :-) Obviously some do... - ELiot
Re: [linux-audio-dev] Cross platform mixer API?
Eliot Blennerhassett [EMAIL PROTECTED] wrote: Greetings, I am aware of PortMixer, which is a simple API that abstracts volume controls. Is anyone aware of any other crossplatform, cross-API mixer abstraction layers out there? I think Eliot's after a hardware mixer abstraction, ie. something to abstract away the hardware gain controls etc. Remix is an application library for multitrack/multchannel pcm sequencing in software; I don't think it's what Eliot's after. Conrad. Correct on both counts Conrad.
[linux-audio-dev] Cross platform mixer API?
Greetings, I am aware of PortMixer, which is a simple API that abstracts volume controls. Is anyone aware of any other crossplatform, cross-API mixer abstraction layers out there? AudioScience is looking for/considering building a library that will wrap ALSA, audioscience HPI, windows WAVE, WDM mixers in a common API. If such a library doesn't exist, why is that? 1) Too hard 2) Too easy 3) No use 4) other? I'd welcome your comments. regards Eliot AudioScience Inc.
[linux-audio-dev] Writing a driver for this card: your thoughts?
Hello, I work for AudioScience (www.audioscience.com) We make excellent (how could I say otherwise) audio cards. The emphasis within the company has been on microsoft windows drivers. ... but we have a Linux driver, currently proprietary, closed source, that exposes this (http://www.audioscience.com/internet/download/spchpi.pdf) API. (It may be possible to release the host side code, but never the DSP code on the cards.) I think it would be much better if we had an ALSA driver. I'd like some idea how hard it would be to write an ALSA driver either as a compatibility layer on top of our existing driver, or from the ground up. I realise that this is rather a broad question, so please consider this an invitation to enter discussion, rather than a request for you to go off and do a lot of work for me. Oh - what do you think of the cards' feature set? Some distinctive things about our cards (not all have all features) - they have on board DSP. Code is downloaded by the driver. - they have a lot of on board buffer memory (hundreds of K at least) - on board DSP handles decompression/compression - mixing - samplerate conversion or multiple outputs at different rates - analog and digital audio I/O, balanced drivers = Eliot Blennerhassett *:-{) AudioScience, Inc.
