I agree, it isn't wanted for every song. I use to call it Paul McCartney vocal... :-) Best schiavoni

[OT] apologies for cross-posting

by Charles Henry

I really wish everyone would stop saying they "apologize for cross posting" to multiple lists. It's dumb. It's a common practice. So why would you want to apologize for it? What fraction of list readers are actually bothered by cross posting? What other activities do you apologize for, as you're doing it? "Uhhh... I know I'm not supposed to do this, but I'm going to--I'm sorry--do it anyway." If it's bad ettiquette, you wouldn't be doing it in the first place, right? People know the difference between relevant announcements and spamming. If I need to know if a message has been cross-posted, I check the recipients. This is just my opinion: all I can do is try to convince you not to keep spreading the word virus. Chuck Note: this message was not cross-posted, even though I considered it :)

Hi Julien and folks There is an old trick to help to "tune" vocals. You replicate your vocal track twice. In one of the copies you add a LADSPA Rubberband pitchshift with +5% and to the other you add the same plugin with -5%. Mix these untunned channels with a low volume, like 20% of the original one. How this workaround help? Once that you try to reach a note, you have 3 chances to it. Our earing will listen only the right one. Normally 5% of pitchshifting is enought to correct small mistakes. Take care to not put the replicas too loud. Cheers Flávio Schiavoni

LAM: A new work in progress..

by James Stone

Hi everyone, This is a short song I put together as my first foray with mixbus. As you can probably hear, my abilities at mixing are only trumped in terms of incompetence by my singing! Suggestions on how to improve things would be appreciated! I guess singing lessons are one I can think of! 'fraid it's on soundcloud: https://soundcloud.com/jmstone/haunted/s-I50zd Direct download: https://soundcloud.com/jmstone/haunted/download/s-I50zd Stupidly, I named it "export.ogg". Hope this doesn't annoy people too much! Just in case anyone is interested, the drums are (mostly) the "Rockstock" from Analogue Drums with sfz formatting. I dropped the "popsticks" hihats in instead tho - as they seemed to be a cleaner recording. I sequenced in seq24 and had a separate output in linuxsampler for each drum. Recorded all drums to mixbus in 1 pass - which I was pleased with! However, having all the drums in separate tracks hasn't helped me too much (see point 1) The synth and bass are presets from yoshimi. The badly played rhythm guitar and plucked guitar bits are thru a V-amp2. Vocals thru a sampson C01 and mic100 preamp. My computer and soundcard really struggled with this tho.. I think it's time to upgrade! James

Playing with play-a-long tracks?

by Josh Lawrence

Hi all, I have some play-a-long tracks from Jamey Aebersold that I would like to use for practice. They are setup so that bass and drums are on the L channel, and piano and drums are on the R. Since I play piano, I need only the L channel. Is there any way to "extract" only the L channel out of the recordings? Once that is done, can something be done to the result that would cause it to sound in both R and L channels, like a true mono recording perhaps? I can easily turn the pan control on my mixer fully left, but that leaves a big hole in the right side. I hope this makes sense, if not please let me know. Thank you! Josh -- Josh Lawrence

Just wanted to report that there's an error with the link to the zip: http://roland.entierement.nu/pages/wiimidi-0.7.tar.gz I think it is: http://roland.entierement.nu/pages/wiimidi-0.5.tar.gz (...then you could change also the version number on the info page, 0.7 -> 0.5) Thanks for sharing. Regards P.S: Some yeras ago I started a similar project that was also to be called "wiimidi", but never got time to finish it properly. But at least I got to integrate the Wiimote in Pd and in CLAM. -- Carlos sanchiavedraz * Musix GNU+Linux http://www.musix.es

Promoting Linux Audio

by Patrick Shirkey

Hi, Over the next year I would like to run a campaign across a few different promotional channels. I would like to make a selection of 10 x 10 - 30 second Digital Multimedia Advertisements to advertise Linux Audio and Multimedia solutions. If anyone has any ideas or concepts they think would be entertaining and within the technical abilities of this community to actually produce within a reasonable period of time and not requiring excessive amounts of commitment please can you share them in this thread. If we get some good ideas then we can look at the logistics of producing them. IMO, the ideas that are the most entertaining and probably humorous will probably stand the greatest chance of getting selected to be produced. Cheers -- Patrick Shirkey Boost Hardware Ltd

[OT] Open Source Portable Recorder?

by Johannes Kroll

Hi all! This is kind of off-topic here but I thought if there is such a thing, some of you guys might know. I'm looking for an audio recorder where the firmware and/or the hardware is hackable. Ideally, this would be similar to the Tascam DR-05 in price and features, but with free/libre firmware and hardware. Maybe someone knows of such a project? Alternatively, is any of the "closed" devices such as the Tascam DR-XX known to have modifiable firmware? Thanks for any pointers! Johannes

Stripping audio from YouTube .webm files

by Ivan K

I am able to download .webm files from YouTube with the youtube-dl utility. Now, I would like to be able to take just the audio track of such a file and write it to a .ogg or .mp3 file. Can someone coach me how to do this? Thank you for your help.
