Re: finding a good audio interface

@tatch: yes, usb-audio chipsets of the FEW companies which do them (for example the VT1620A isnt highend though) - I always saw linux as perfect source of generic info about hardware support, as MANY companies do products based on FEW the same chipsets in fact, some based on fair reference-designs, ...

Re: USB 2.0?

Then, as a subset of USB standards, there is USB Audio Class 1 (with limited sample rate) and Class 2. Errr... right? ya, USBx.0 is in fact physical layer and signaling specification, having 1.1 as bugfix to 1.0 in fact, there was some early consumer skypephones 1.1 chips but for even better behavi...

Re: Experiment

@all: thanks for the big-pictures and detailed internals on linux audio elsewhere;

One question, tried anybody to benchmark at least most complete(?) ardour somehow?
When I tried to b/g "ardourVST DAWbench", there is till now NOTHING to return, curious :-)

Re: eDrummer beta

@jeff: honestly, if jack internal "tick" of processing audio blocks is bound to "-p" (async adding exactly ONE more such buffer only??), then having 16 here, its 16/48000 for example, so 0.3ms; then if everything jackd needs to do against all connected clients fits in 0.3ms (not ...

male, kindly please, is there something for linux like this to "really measure" in/out roundtrip latency?

Re: eDrummer beta

Honestly, from everything I read during many hours as quite uninformed win user, I also think that JACK is quite good compromise between flexibility and low-latency vs pure ALSA with slight higher CPU use. I understand you Jeff, but if JACK already does lot of hard work even to use ALSA MMAP where a...

Re: eDrummer beta

@jeff Absolutely no JACK. I completelly understand you want to omit everything not necessary, at least to save CPU cycles, but what about implementing your own output lib (separated, with on/off each target?) which will allow even simultaneously send samples with priority to ALSA for "almost di...

Re: eDrummer beta

A proper pad must be designed so that there is only one trigger per "human action". Umm, my idea is that its up to the host to proces data from more sensors to translate to information from single pad. More sensors I mean for positional sensing - so for the "surface" at least 3 ...

Re: Sneak Preview: LV2 Create

@ssj71: thanks, ya, it seems I understood the modularity already from many forum posts here, its OK @male: I completly agree that host-generated UI is perfect, having good metadata/discoverability from plugin (not knowing details); only pro-engineers out of this nice little linux things often want r...

Re: eDrummer beta

WOW. Well, guys, I finally understood that Jeff is more considering "embedded" linux usage and here his complains about anything bigger than plain ALSA and simple plugins, this is OK. Hope I can add my 2c here too, as relistic eDrums is thing which I am researching for years already - not ...

Re: finding a good audio interface

hi, to add some generic info some of noted models are probably based on such USB2.0 FULL-speed (usb-audio 1.0 class) chips : http://www.cmedia.com.tw/ProductsIndex/ClassifySerno-26.html (you see CM65xx = one-way 24/96 etc, due to 12MB/s bandwidth) or those: http://www.via.com.tw/en/products/audio/us...

Re: ALSA, JACK and other approaches (e.g. Windows Audio Syst
