[linux-audio-user] Clicks/pops in recording

by Chris Abbott

Just recently I recorded a live piano concerto. All of this was done using an ART Pre-amp, a Soundphone(I believe is the brand) CD burner, M-audio Omnistudio USB, and an iBook G4. Now, the pre-amp had a digital out that went to the CD burner. The 1/4" outputs of the pre-amp went to the M-audio which was connected to the ibook. Well, the burned CDs turned at great(note-I had the digital sample rate set to 48Khz). I had my Omnistudio set at 96Khz. Every so often in the recoding, you hear a bit of pop, which to me seems like some other system resource got priority. The only thing that occurred while recording was the display going to sleep. The airport was off, and Ardour, X11, and JackPilot were the only programs running. I'm curious as to what could have caused this, how to fix it. The next time I do a recording with it, I will probably have to drop the sample rate to 48Khz. -Chris

[linux-audio-user] M$/SuSE/ALSA ?

by Dave Phillips

Greetings: As many of you already know, SuSE has entered into an interesting 5-year plan with Microsoft. You can find the details on Slashdot and elsewheres, so I won't rehash them here. What isn't mentioned is the ALSA/SuSE connection. I'm pretty sure some of the ALSA developers read these lists, and I'd like to hear from them regarding the significance of their employer's new connections and ALSA's IP and its continued development. Is this marriage happy news for Linux sound or is it an unholy alliance signifying doom and destruction for the world at large (and not just the Linux audio community ;) ? Or will things just cruise along in business-as-usual mode ? Any and all insight vastly appreciated. Best, dp

[linux-audio-user] Dave's Prelude

by Gavin Stevens

I must've downloaded Dave Phillips' Prelude a while ago & then not listened to it. Finally corrected that oversight & greatly enjoyed it - nice harmonies. In fact, a piece with a quiet, almost veiled beauty. I wonder if it would work on an acoustic piano (although it sounds nice with the bell piano)? Thanks Dave - I look forward to more. Gavin.

[linux-audio-user] Re: The famous "Jack Hum" (Can't > record and desparate )

by Geoff Beasley

another serious candidate for this kind of hum are "wall wort" power supplies.they can radiate AC hum for up to 2-3 meters from source. Do your speakers have power this way ? move the power supply towards and away from any audio hook-up cable and see ! best, g.

[linux-audio-user] reverse reverb

by Atte André Jensen

Hi I'm looking for a "reverse reverb" effect to use in ardour. I'm not sure what the appropriate term is, but on an old analog tape it could be achieved by butting the tape in "wrong" so that it plays back in reverse, running the sound through a reverb, recording the reverb to separate tracks and putting the tape back in for normal playback. Is such an effect available as a LADSPA plugin (in that case I apologize for being unable to spot it in the vast list of plugins), or could it be build/emulated by using several LADSPA plugins? -- peace, love & harmony Atte http://www.atte.dk | quintet: http://www.anagrammer.dk | compositions: http://www.atte.dk/compositions

[linux-audio-user] Ardour, Recorded Track in advance

by Lilli Chiffon

Hi the list, My apologize for all this noise tonight from me. I still have a little problem with ardour. When i record a track, from analog material (my guitar to be precise), i play with a click and i'm on the time. But when i'm listening the result, it's allways a little bit in advance (i can hear it) I compiled my kernel with realtime and preempt patch and when i run ardour and jack, ardour indicate a 0.7 ms latency time but jack setup latency is 92.7 ms. For the moment i move the region to fix it, but it's very usefull. Is there someone to met this problem before ? Cheers P'tit Louis
