[linux-audio-user] Sample Rates / Sample Sizes

by davidrclark＠earthlink.net

Starting a new thread originating as: Re: producing a drum sample library for hydrogen I can easily tell the difference, as can many, between 16- and 24-bit samples, but not equally for all instruments, of course. I highly, highly recommend using 24-bit samples for any widely used library, especially given the amount of processing that most of us do. I myself also use 96,000 samples/second because I always do quite a bit of processing, but that's a lot tougher sell for a library. --------------------- Someone said that 44,100 samples/second is a quirk. It's not merely a quirk. 44,100 = 2^2 * 3^2 * 5^2 * 7^2 which has some useful properties compared to 48,000 = 2^7 * 3 * 5^3. Lots of small primes that differ is sometimes better than a bunch of powers of two, despite the advantage primarily associated with FFT's that some focus on. Looked at from a prime number standpoint (therefore certain types of algorithms), 48,000 is truly bizarre compared to 44,100. 96,000 is yet ANOTHER power of two on top of 48,000! Whether a particular sample rate is a good one or not is dependent upon more than just what is customary and standard.

[linux-audio-user] running gag: m-audio quattro

by metafor＠gmx.net

hi list i followed the instructions to get the card working (thanks josh) but i'm still don't get any results. i've patched the kernel 2.6.5-mm4 with the two patches mentioned on the list. i can load the snd-usb-audio module, dmesg means that it's registered (module) , but i don't get this error-messages: config 1 interface 1 has no altsetting 1 config 1 interface 2 has no altsetting 1 config 1 interface 4 has no altsetting 2 config 1 interface 5 has no altsetting 2 config 1 interface 7 has no altsetting 2 config 1 interface 8 has no altsetting 2 is there a way to see if the pc atleast realise that there is a card conected? any module which has to be loaded beside snd-usb-audio? by the way i can't compile nvidia with this patched kernel, running nv therefore, anybody already solved this OT? are this 2 special patches http://marc.theaimsgroup.com/?l=linux-usb-devel&m=108178375704810&q=raw http://marc.theaimsgroup.com/?l=linux-usb-devel&m=108178386018353&q=raw allredady integrated in some standard kernel release and also the mm4? i could then go directly to 2.6.6 or 2.6.7 which would solve also my nvidia problem. sorry to bother you again with this quattro issue, but if someone can give a simple step to step advise, it would be really helpfull. thanks marc

[linux-audio-user] Multi I/O sound card needed

by Jos Laake

Hi again, I'm considering getting a good professional quality soundcard. Anybody want to plug their favourites? I've been watching e-bay and there are always M-Audio Delta 44's and Delta 66's available. Any other good cards out there to keep my eyes open for? Also, I'd like to use the spdif I/O on the card I have, to reduce the computer noise on the audio inputs, but all of the outputs on my outboard gear are analog. Can inexpensive audio to spdif adaptors be found? I've been searching, but have come up with zip so far. Okay, thanks again in advance. ~Jos~

[linux-audio-user] mcontrol-0.0.01

by holborn

Hi I released this small utility ... and sorry for the English :-) Overview --------------- mcontrol is a ALSA MIDI sequencer client and brings the possibility to assign up to twelve "simultaneous" MIDI control messages for each controller in your MIDI keyboard (Modulation Wheel, Breath Controller, Foot Controller, Pitch Bend and After Touch). An example is always better: You can send Reverb, Volume, Chorus, Modulation MIDI messages using the modulation wheel controller of your MIDI keyboard. Or pitch bend and reverb using after-touch, or control the Filter Cutoff in modulator wheel, or control the Pan using the Pitch Bender ..... etc etc etc ... Most of the moderns synthesizers can do that, but normally don't send the midi data, with mcontrol you can record series of controllers in your favorite sequencer. Up to 200 Midi message controllers, can be edited and saved. And programs and Banks of 45 programs of what you edit can be saved too. availabel in: http://personal.telefonica.terra.es/web/soudfontcombi/mcontrol-0.0.01.tar.gz Please check, sure they will be tones of bugs :-) Requirements: --------------------- * Linux (Tested on a PIII 933 Debian sid and PII 300 Gentoo). * ALSA (with sequencer). * FLTK (tested and compiled with v1.1.1) * Midi Keyboard (optional) Josep

[linux-audio-user] Anyone using RTSynth ?

by Alastair Couper

I am trying to get RTSynth to work. The audio output is apparently not getting connected to alsa properly. When I hit the on button, I get the following error message: Sample format not available for playback: Invalid argument Alsa is running fine, just this app complaining. Any ideas ? Thanks AC

Hello List Not really what we're for, but - in transcribing my vinly I've found one with a blob of candle wax on it (covers about a 1/4" diameter) What's the best way to remove this? Cheers Dylan -- "I see your Schwartz is as big as mine" -Dark Helmet

[linux-audio-user] perfect pitch application

by Florin Andrei

Anyone knows an application (for Linux) that can take the sound of a single instrument (or voice, or anything that's simple - not complex sounds) as an input, and transform it into notes (or a MIDI file)? Essentially, it's what a musician with perfect pitch does - upon hearing a melody, start playing it on an instrument. Or, if you wish, the reverse of a softsynth: from WAV to MIDI. I'm pretty sure i've seen something like that advertised somewhere ("Sound On Sound"? "Keyboard Magazine"?), and i'm pretty sure it's not for Linux, so i wonder if there's something similar on Linux. -- Florin Andrei http://florin.myip.org/

There is no much space in the front of hit, but I have seen samples where the cut is too much. An extra fast artificial slope makes the sound kick, but it is unnatural. Extra space at the start does not make harm. Software can set the zero position deep in to the audiofile if one wishes. >A second version of the library could be for surround >where anything is open for debate. Incidentally, I The major motto in my sound library project is that the raw samples are most important because everything else can be done later -- better than you and me can do. (So, I'm happy as long as I get the raw unprocessed recordings.) Making this a lot of pre-effected samples is an old-fashioned way. Now one should provide only raw samples and a software for making effected and spatialized sounds. Say, I could have a footstep sound and use software to make a person to walk in the room. Current sound libraries have sound such as "walking from left to right" --- quite boring actually. >What reverb instruments do you have? >I've got Lexicon LXP-15, TC Works and Waves. I have written my own. I thought to try something which those reverbs don't provide. Juhana

Also the time take to compose a typical forum message > is massivly higher than replying to a list - though that way be a point in > forum's favour ;) The email notification function on the forums I'm suscribed to supersedes my erasable memory: each time the thread I've been posting to gets an update, I receive a link that leads me directly to the first unseen message, with the previous just above! I must admit the only use I find in the mailing-lists' batched daily digests is having a look at the threads having been refreshed: I can't then do anything else but browsing the archive, unless it's more like a crowd cross-talking upside-down! Some other arguments in favour of forums? - sorted by folders... while here all hardware, installation or general issues are muddled up. - no need to lose archival space with infinite quotations, but still the abilty to quote short sections when needed! - advanced writing capabilities: not that I'd hate ASCII art, but using underlined or bold words, ordered (or not) lists, enhances the ideas exchange, so that the reader can oversee faster the issue. (But lose those ugly emoticons please! ,-) - less dependent of the user's client: it seems that each time someone here has a signature beginning with 2 dashes "--" followed by a carriage return, my email client (online ISP built-in Horde IMP) can't understand it correctly and "shadows" all the following messages! (Plain text, not HTML-enabled) And this client definitely cannot respect the thread tree... When it comes to forums, Once php is supported, browsers won't groan! - rewritable media: writing long messages (like now) compells me to use a notepad to avoid failure whenever the email session expires. (I don't like using hard-drive installed email clients due to the many times I'm not at home.) On forums, I can store the message temporarly by previewing it, without rushing on the keyboard; and correct my mistakes after the first "official draft". - browsing a user's profile to find all the threads he's created or fed, when you know you're usually reflecting yourself on his words. Enough said... What's the best of both worlds then? Cheers Christian Frisson (the one for mailing-lists) aka Mr°Freeze (staying anonymously cloaked on forums)

I do know what you mean, but it seems to me that the mainstream computer musician with a Mac or PC tends to use web forums as well as, or instead of, mailing lists. Maybe this is because most of these people only started using the internet after the browser was invented, who knows? Cheers Daniel
