And the genious thing about it is not hidden in the code, but visible in the user interface, so maybe someone will make an open source alternative, it shouldn't be that much work. It doesn't work with jack (or jacklaunch) either, so an open source alternative is really needed.

[linux-audio-user] transcribing software?

by Josh Lawrence

Hello all, I'm in the process of trying to transcribe some solos off of a Yellowjackets album. It's an up-tempo blues number, and some (well, most) of the notes are going by way too fast. I would like to find some software to slow the tune down so I can hear the lines a little better. I did some googling last night, and I found this: http://www.seventhstring.com/xscribe/overview.html But it is a commercial solution, written primarily for Windows, with Linux seeming like an afterthought. Searching google groups didn't come up with anything, either. Can someone recommend something native to Linux that can do time-stretching for transcribing purposes? Thank you, Josh -- Josh Lawrence http://www.hardbop200.com

If so, you can use Audacity > http://audacity.sourceforge.net and apply such effect to your track. Here's an old school idea: I used a '56 Garrard turntable for transcribing (Yellowjackets, "Samurai Samba" about 1985). Why? Because it had 16 rpm as a speed, which drops you to almost exactly an octave lower, but half the speed. You can do this with a DAW by playing back at 1/2 sample rate, and it's much easier to get the notes, plus the artifacts of pitchshifting are non-existant. (You don't mind the info loss -- you're listening for content, not sound quality. When you go back to speed, everything seems to make so much more sense. Cheers, Phil M (In reverse, this is how the Earth, Wind, & Fire horns were recorded -- an octave low at 1/2 speed -- to make them seem so tight!) -- Dept. of Mathematics, 342 Machray Hall U. of Manitoba, Winnipeg, Manitoba, Canada R3T 2N2 Office: 446 Machray Hall, 204-474-6470 http://www.rephil.org/ phil at rephil dot org

[linux-audio-user] [ANN] netjack-0.9 with alsa I/O (also can be used to bind jackd to 2 soundcards)

by torbenh＠gmx.de

ok... netjack-0.9 is here. this is basically netjack-0.9rc4 with the transport offset of one period fixed. additionally i have added 2 jack clients which open unrelated soundcards. these are fixed reimplementations of the old alsa_client. fully configurable, and better than the alsa_client. it does even work with usb soundcards. using a second soundcard for monitoring purposes is now possible. the only current limitation to this is 16bit. but this will be changed soon... -- torben Hohn http://galan.sourceforge.net -- The graphical Audio language

[linux-audio-user] [ANN] Csound 5.01 release

by Istvan Varga

Source and binary packages can be downloaded from here: http://sourceforge.net/project/showfiles.php?group_id=81968 The following Linux binaries are available; these all include the HTML manual as well: Csound5.01-i386d.tar.gz this was built on SuSE 9.3 (x86, GCC 3.x) with double precision floats, and includes a simple GUI installer Csound5.01-i386f.tar.gz same as above, but with single precision floats Csound5.01-x86_64d.tar.gz same as Csound5.01-i386d.tar.gz, but for the AMD64 platform Csound5.01-x86_64f.tar.gz same as above, but single precision floats Csound5.01_i686.rpm an RPM package built on SuSE 10.0 (x86, GCC 4.0) with both single and double precision floats, and includes the following additional features that are not available in the .tar.gz packages: * csoundapi~ object for PD (32 bit floats only) * CsoundVST (GUI frontend and Python module for algorithmic composition; 64 bit floats only) * STK (Perry Cook's Synthesis ToolKit) opcodes * VIM files for syntax highlighting and keyword help --------------------------------------------------------------------------- Changes since Csound 5.00 ------------------------- New features: Made it possible to load opcode plugins only when the opcode is actually used. New opcodes: New track processing opcodes for PVS system: trscale - streaming partial track frequency scaling trshift - streaming partial track frequency shifting trsplit - takes an input containg a TRACKS pv streaming signal and splits it into two signals according to a k-rate frequency 'split point'. trmix - takes two inputs containg TRACKS pv streaming signals and mixes them into a single TRACKS stream trfilter - filters a TRACKS pv streaming signal using an amplitude response curve stored in a function table trcross - streaming partial track cross-synthesis trhighest - extracts the highest-frequency track from a streaming track input signal trlowest - extracts the lowest-frequency track from a streaming track input signal binit - PVS tracks to amplitude+frequency conversion barmodel - creates a tone similar to a struck metal bar max - produces a signal that is the maximum of any number of input signals min - produces a signal that is the minimum of any number of input signals maxabs - produces a signal that is the maximum of the absolute values of any number of input signals minabs - produces a signal that is the minimum of the absolute values of any number of input signals maxaccum - accumulates the maximum value of audio signals minaccum - accumulates the minimum value of audio signals maxabsaccum - accumulates the maximum of the absolute values of audio signals minabsaccum - accumulates the minimum of the absolute values of audio signals Changes: Several opcodes and opcode groups have been moved out of the Csound library and stdopcod library into separate plugins (vbap, babo, grain4, hrtferX, PhisEm opcodes). Improvements in JACK plugin to allow lower latency and remove some restrictions on buffer sizes. Bug fixes: Bug fixes in FLsetVal and FLsetVal_i; allow buttons and button banks in FLsetVal; fixed handle output of FLbutBank (not sure if this is safe); implemented cursor size parameter for FLknob. Fixed bugs in i-rate ZAK opcodes. Fixed hang on very short note before end of score or section. Added hacks to fix the problem of the else branch of an if/then/else always being executed at i-time. Fixed crash on 'then' or 'goto' in variable names in conditional expression for if/elseif. Fixed crashes on missing whitespace between if/elseif and '(' and on extra ')' in expressions. and of course a number of minor bug fixes all over Changes: 2006-03-16 Istvan Varga <ivarga(a)csounds.com> * Opcodes/sftype.h: check for MacOS 9 or PowerPC, and define WORDS_BIGENDIAN on those platforms. 2006-03-13 Anthony Kozar <anthonykozar(a)sbcglobal.net> * Top/main.c: Made TYP_AIFF the default for MacOS 9. * Engine/entry1.c: Removed duplicate OENTRYs. 2006-03-12 jpff <jpff(a)codemist.co.uk> * Opcodes/bilbar.c (bar_run): Corrected boundary condition 2006-03-11 Istvan Varga <ivarga(a)csounds.com> * Engine/express.c: fixes in extending tokenstring buffer 2006-03-10 Anthony Kozar <anthonykozar(a)sbcglobal.net> * Opcodes/minmax.c: * SConstruct: Added new 'minmax' plugin library with opcodes for finding minimum and maximum values among several signals. 2006-03-10 Michael Gogins <gogins(a)pipeline.com> * CSD style command lines in CsoundVST are now translated to orc/sco style before performance in order to save having to edit the command line after loading some CSD files. 2006-03-08 Istvan Varga <ivarga(a)csounds.com> * Made it possible to load opcode plugins only when the opcode is actually used. 2006-03-07 jpff <jpff(a)codemist.co.uk> * Engine/otran.c: Removed DTYPE and lclnxtdcnt as not used 2006-02-25 Michael Gogins <gogins(a)pipeline.com> * Updated SConstruct, custom.py, and Windows installer to build and install PortMidi. 2006-02-24 Istvan Varga <ivarga(a)csounds.com> * InOut/rtjack.c: Use thread locks instead of calling usleep() in a loop to implement blocking I/O; the -+jack_sleep_time option is now deprecated and ignored. Allow non power of two values for -B. Setting -b to the same value as the JACK buffer size is no longer required. * Engine/insert.c: * Engine/musmon.c: Alternate fix to problems on very short (less than 1/2 control period) notes; the previous fix introduced a new bug that resulted in early termination of the score in some cases. * H/version.h: * installer/misc/csound.spec.in: Updated version number from 5.00.1 to 5.01.0 to reflect the addition of new opcodes. 2006-02-24 Victor Lazzarini <Victor.Lazzarini(a)nuim.ie> * Opcodes/psynth.c new track processing opcodes (also added manual pages): trscale, trshift, trsplit, trmix, trfilter, trcross, trhighest, trlowest, binit. 2006-02-15 Istvan Varga <ivarga(a)csounds.com> * InOut/widgets.h: moved file from H/ * InOut/widgets.cpp: bug fixes in FLsetVal and FLsetVal_i allow buttons and button banks in FLsetVal fixed handle output of FLbutBank (not sure if this is safe) implemented cursor size parameter for FLknob 2006-02-13 Istvan Varga <ivarga(a)csounds.com> * OOps/ugrw1.c: fixed bugs in i-rate ZAK opcodes 2006-02-09 Istvan Varga <ivarga(a)csounds.com> * Engine/rdorch.c: splitline(): made checking for invalid characters stricter fixed labels before else/endif allow bitwise NOT operator in UTF-8 format 2006-02-06 Istvan Varga <ivarga(a)csounds.com> * Engine/entry1.c: cogoto requires an i-rate conditional * Engine/musmon.c: fixed hang on very short note before end of score or section * Engine/rdorch.c: added hacks to fix the problem of the else branch of an if/then/else always being executed at i-time.

[linux-audio-user] Aligning audiofiles for different recorders.

by Alex Polite

Howdy I make a lot of interviews. Right now I have a two channel recorder. I connect one headset mic to each channel, put one on myself and one on the interviewee. Works kind of alright but I would rather have the interviewee wear one recorder and wear another myself. This gives us more freedom to move around during the interview. The tricky part will be to align the two separate recordings. I could probably do it manually in ardour, dragging the regions back and forth and stretching them until they line up exactly. I've googled a bit to find a tool that does this aligning automatically but haven't come up with anything. Does anybody out here know of something? alex -- Alex Polite http://flosspick.org - finding the right open source

Ha ha ha ha! Oh man. Considering the vmware modules are closed source, that is 100% their problem, not your favorite distro's.

[linux-audio-user] Simple scripting language to use for audio processing?

by Alex Polite

Ok, since I can't find a tool that will automatically align two audio files, I think I might write one my self. What scripting language has the best modules for audio processing? I'm have pretty good at python and halfway comfortable with ruby, perl and java. I've looked at pythons wave module put it looks a bit crude. alex -- Alex Polite http://flosspick.org - finding the right open source

I admit that was not the best of examples, but my point was simply that there are people who find listening to racist screed every bit as distressing and offensive - or even more so - as having to breathe second-hand smoke. The one - a physical abuse, the other - a mental and emotional one. > You have misinterpreted the posts on that subject. No one said >anything about denying Jamendo the right to censor others on their site. >Most people here just don't agree with censorship and so will not put >anything up on Jamendo. Given what this list is about I think that's a >perfectly understandable bias ;-) If this whole discussion was just about whether Jamendo is a good place to publish music given their censorship policies - then yes, I did misunderstand. (I thought some people were trying to make the case that it is wrong to limit the speech of others anywhere under any circumstances.) >Free speech never intrudes on the rights of others unless it incites >people to commit acts that intrude on the rights of others. As Mark >pointed out, yelling "Fire" in a crowded theater is not acceptable. >Asking people to kill other people in the name of whatever is also not >supported free speech. I would have to take exception to making this distinction for two different, and seemingly opposite reasons. Sometimes, people's exercise of free speech - say in certain communities whose purpose is to cultivate a friendly and cooperative atmosphere based on shared interests and objectives - creates a poisonous atmosphere which is inimical and totally antithetical to the purpose of that association of people. For example: a fundamentalist Christian goes on a metaphysics forum, disrupting every single thread - thumping their bible, ranting that everyone there is going to hell, and trying to shut down the forum with spam, dos attacks, complaints to the isp, etc. This kind of behavior - while not dangerous, and within the scope of free speech - is clearly disruptive and detrimental to the purpose of that community and it would be reasonable to deny such people access to the forum. (This being an example, btw, that I have actually encountered a number of times.) The argument that free speech is unacceptable only if it seeks to incite physical action of a violent or harmful nature is contradictory to the assertion - made by some here - that it is insulting to people's intelligence to suggest that they can't discern the truth for themselves and need to be protected from those spreading malicious falsehoods or antisocial viewpoints. If people are to be credited with the intelligence to decide for themselves what they think of someone else's viewpoints, they should also be credited with the intelligence to decide for themselves if they want to go out and lynch people, bomb synagogues or mosques, or whatever. Words can't *make* people do things. People *choose* to do things and are solely responsible for their actions. (My point here is simply that in the 'public' arena - *all* speech should be protected, even if it advocates violent behavior, and in a *private* environment, a case can be made for restricting speech even when it does not cause or incite physical harm.) In Jamendo's case it is debatable whether their choices of content to exclude are constructive or not. If they allow all content, they are sure to turn away some users, and if they deny certain content, they will likewise turn away many users. I would imagine they made their decision based upon either a pragmatic calculation as to which course would turn away the least number of users, or simply informed by their own personal ethics and what they wish to be associated with. For me - the more freedom and tolerance the better for all concerned. For those disagreeing with Jamendo's policies - perhaps it would turn out to be constructive to contact them regarding their views. They just might decide to change their policies if there are enough people in the community voicing concern about those policies. Cheers, Maluvia
