RE: [linux-audio-user] wav editor that does not require alsa

(I'll ask in this list if that fails :) Like mik mentioned, you will probably want to used GCDMaster for creating the CD tracks. It supports features like allowing you to set track and indexing points without having to chop up the file into multiple files first. The real benifit from this is if you happen to be doing a live cd. GCDMaster uses a 74 frame/sec time code like CDs do. That allows you to set a track right on a frame so that you don't have padded tracks, or worse loud popping noises between tracks. Even if you're not doing a live CD, it's still very handy for audio CDs. -Reuben

[linux-audio-user] install agnula demudi on the HD

by sigir

I've burned Agnula Demudi on a CD and put it in my laptop. It works like Knoppix, it seems, but I did'nt find any install. How can I install Demudi on the hard disk ? Thank you -- sigir

[linux-audio-user] Rack-mountable external sound-card boxes.

by Luke Yelavich

Hi all I am wondering whether it is possible to remove the screw holes on either end of a studio rack-mountable soundcard box? Thanks Luke -- Luke Yelavich http://www.audioslack.com luke(a)audioslack.com

[linux-audio-user] emi26 on ppc

by stefan kersten

hi, a variation on the usb audio interface theme: i recently tried the emagic emi2|6 on my powerbook (tibook G4, debian/unstable/2.6.5), with only partial success. the device is detected, the firmware apparently loaded, and snd-usb-audio appears to successfully claim the interface. however, when i try to use it with jack, jack bails out because it cannot find any usable sample format. when playing a soundfile with alsaplayer, i just get noise; sounds like an endianness problem. sorry, i can't post any output, as i don't have the interface at hand. i just wondered if someone has a working configuration for the emi26 on ppc hardware. maybe some asoundrc magic is enough? tia, <sk>

Re: [linux-audio-user] MP3 streaming via JACK.

you could use icecast2 and libshout as a source for icecast :) i havn't got around trying it but here is a link http://xiph.org/~karl/ -- Marko Dimiskovski > Hi all > Does anybody have any idea about what I could use for streaming audio via > MP3 from JACK apps?

This got me further but unfortunately did not entirely resolve the problem. Now I do get 24-bit capture and 16-bit playback. But only with 2 channels of each. :) If I do not set the -i 2 switch for Jack I get only silence in the output ports. With 2 i/o channels I get the correct bit depths for both so the configuration above seems to be right. The rest may well be emi-spesific. I'll keep experimenting. -Jorma __ Sano ei kuukausimaksuille. Hanki Suomen edullisin kuukausimaksuton GSM-liittymä osoitteesta http://www.saunalahti.fi. Puhelut vain 0,109snt/min.

[linux-audio-user] 2 audio cards with Red Hat 9.0?

by millward

Is there a way for Red Hat 9.0 to switch between two different sound cards? I've got an ASUS A7N8X motherboard that has on-board audio. It's a Realtek ALC650 6CH with built-in HP amplifier. This is what Red Hat identifies now. I need it for DVD movies and audio CD since it can be connected to my CD-R/DVD-ROM drive. But for recording, I have an Audiofile 2496 PCI sound card. It's in the machine now, but Red Hat does not recoginize it. There doesn't seem to be any way for the CD-R/DVD-ROM drive to connect to the Audiofile 2496 PCI sound card. Is there a way for Red Hat 9.0 to recognize both at the same time, or to switch between them?

[linux-audio-user] Delta 1010LT and recording question

by H. T. Hind

Hello, I'm using a Delta 1010 LT card to record from radio tuners. How does one record from all 10 inputs ? I see 8 Analog inputs and two digital. How can I use the two digital ports to record ? Do I need special adapters ? When I plugged the line-out from a audio-source to the S/0 port, I didn't see anything in envy24control . I'm using JACK and ecasound to record the individual channels to individual files. As the Delta 1010 seems capable of stereo recording , is it possible to record 20 line-ins in a mono mode ? If so, how do I split it ? I bought a couple of adapters from Radio Shack such that I can connect 2 cables to the analog-in of the delta-1010 ? Is it possible to then route the invididual channels to individual files ? hth --

[linux-audio-user] Firewire audio support?

by Samuel Thurston

I am in need of an external audio interface for my laptop. I want it to be firewire, and I currently use both linux and windows for audio(dual boot). I was strongly considering the M-Audio Firewire 410: http://m-audio.com/index.php?do=products.main&ID=5f35def5b4107998b111199070… <http://m-audio.com/index.php?do=products.main&ID=5f35def5b4107998b111199070…> But I don't see it on the ALSA compat. list. Anybody have any good suggestions? I want something that is compatible with Macs as well, since I think that's where I'm headed.
