[linux-audio-dev] Software with source code?

by Juhana Sadeharju

Hello. I have partially lost the track on the latest audio and graphics development. Even I'm on 50+ mailing lists, the whole picture is blurry. So, I'm making a list of software which comes with source code. The list is intended more to developers who are looking for example codes, library codes, and projects to join. An unfinished list follows. The list format is simple: name and description. That is because one must be able to read the list through line-by-line without getting bored to details. Maybe later I will fill in the details: what re-usable gizmos the software have (filters, drawing algorithms, etc).

I dont know who has them now. Me - I've traded a few emails with the Yamaha mLAN licencing manager and he's been promising to get us in touch with a guy at Rhodes University who's been working on mLAN driver support. Once I'd made contact with him I was going to pass the details onto Bob et al. Be good for us to get all of these contacts working together. R

[linux-audio-dev] libfishsound-0.6.0

by Conrad Parker

Hey LADs, if you're looking for an easy way to add Ogg Vorbis and/or Speex support to your apps, check this out :) It's lightweight, callback based and uses per-channel float arrays by default (ie. the format preferred by JACK and LADSPA). It's fully documented, tested cross-platform, and includes examples for doing Ogg Vorbis and Speex decoding (~100 loc) and encoding (~110 loc). FishSound 0.6.0 Release ----------------------- libfishsound provides a simple programming interface for decoding and encoding audio data using Xiph.Org codecs (Vorbis and Speex). This release is available as a source tarball at: http://www.annodex.net/software/libfishsound/download/libfishsound-0.6.0.ta… libfishsound by itself is designed to handle raw codec streams from a lower level layer such as UDP datagrams. When these codecs are used in files, they are commonly encapsulated in Ogg to produce Ogg Vorbis and Speex files. libfishsound is a wrapper around the existing codec libraries and provides a consistent, higher-level programming interface. It has been designed for use in a wide variety of applications; it has no direct dependencies on Annodex or Ogg encapsulation, though it is most commonly used in conjunction with liboggz to decode or encode Ogg encapsulated Vorbis or Speex files. FishSound has been developed and tested on GNU/Linux, Darwin/MacOSX and Win32. It probably also works on other Unix-like systems via GNU autoconf. For Win32: nmake Makefiles, Visual Studio .NET 2003 solution files and Visual C++ 6.0 workspace files are all provided in the source distribution. Full documentation of the FishSound API, customization and installation, and complete examples of Ogg Vorbis and Speex decoding and encoding are provided in the source tarball, and can be read online at: http://www.annodex.net/software/libfishsound/html/ FishSound is Free Software, available under a BSD-style license. More information is available online at the FishSound homepage: http://www.annodex.net/software/libfishsound/ enjoy :) -- Conrad Parker Senior Software Engineer, Continuous Media Web, CSIRO Australia http://www.annodex.net/ http://www.ict.csiro.au/cmweb/

[linux-audio-dev] Announcing USound, the Useful Sound Daemon, version 0.2.0

by Matt Campbell

USound (the Useful Sound Daemon) is an audio I/O daemon for Unix systems, especially GNU/Linux. It provides low-latency mixing of multiple audio streams with resampling and limited format conversion, as well as audio recording. The package also includes a client library, a libao plugin, and patches for madplay and MPlayer. USound is free software; it is distributed under the GNU General Public License (GPL), except for the client library, which is in the public domain. USound is somewhat similar to the Enlightened Sound Daemon (EsounD); but as the name implies, USound aims to be more useful, particularly for consumer desktop and multimedia applications. Applications for which USound is suitable include media players, audio and video conferencing software, text-to-speech software, and any application that plays the occasional sound file to alert the user. USound is still under development and by no means perfect, but in my (admittedly biased) opinion, it has already surpassed EsounD and aRts in usefulness. The USound home page is at: http://pobox.com/~mattcampbell/usound/ Have fun! Matt (who is listening to an MP3 with USound and madplay right now)

[linux-audio-dev] USB Keyboards

by Jens M Andreasen

Hi! Anybodyelse been shopping around for a USB keyboard lately? How come that the offerings available have just about all of the features and flexibility that anyone would want, BUT when it comes to playability of the keyboard itself, then .. how to say .. then it seems like just another sloppy disaster. I have one (as yet) unpatented idea for a cheap-to-build funky keyboard. Anybody have a workshop? /jens

[linux-audio-dev] Status of mLAN?

by Jody McIntyre

What's the status of mLAN on Linux? I found a few discussions in the archives, the latest being http://eca.cx/lad/2003/12/0084.html , but nothing really conclusive. It seems that there is documentation (and even an implementation) for A/M, but nothing for Connection Management. Has anyone tried recently to get documentation? Based on http://www.yamaha.co.jp/tech/1394mLAN/english/ptt.html , it seems that documentation is available for a nominal fee, but it is more than I am willing to pay. I am considering buying a PreSonus FireStation, which does what I need at half the cost of an RME Hammerfall, and am willing to spend a considerable amount of time writing a driver, if documentation is available. Thanks for any information, Jody

[linux-audio-dev] player suggestion

by Juhana Sadeharju

Hello. After years of waiting, AlsaPlayer succeeded to compile. Here is a report. I post here so that authors of other players can take the hints. Given multiple files, I executed the following: alsaplayer *wav All files are played ok, yes. But when one hits (|<) button the player skips two files back and plays only the two last files. Should it skip to the begin of the last file? Or to the begin of the file list? Not something in between. I also suggest a mode in which the play slider represents the all files concatenated together: o----file1---o----file2----o----file3----o That way one has easier access to all files. The mode would be specially good if one has tens of small sound samples. Also: If I first press <stop>, then why (|<) starts the playing? I just want move to the begin and then play later. So, my suggestion: If player is playing and one presses (|<), it continues playing. If player is not playing and one presses (|<), it only skips to the begin. Further: The playing stops at the end of file, making it impossible to continue scrubbing and speeding infinitely. The player should just stay at the end at the play state. Likewise when playing in reverse direction: player should not go to the stop state at the begin. More: The player played the file and stopped. I moved the play slider to middle and started the play: the player started playing at the begin, not where the play slider was at. Neverending: The playing has been stopped and the play slider is at the begin. I try grab and move the play slider, but nothing happens. I should be able to move the play slider at any point and start playing there. Now playing can start only at the begin. Infinity: After speeding backwards to the begin, the player stopped. Then by pressing play button, I got the following errors and nothing was played: an ERROR occured or EOF (10793). -*- Given that AlsaPlayer has been developed for years now, why I found so many problems? Most of the problems are not technical, but artistic. I have alsaplayer 0.99.76. Regards, Juhana

I would encourage you to hold off for a couple months, of course if you can afford to wait. It took me literally a good year on my old Inspiron 8000 (later replaced for 8100) before most of the quirks were resolved on it (both Win32 and Linux-side). This is pretty much the case with most of the new technology. For instance my newest toy, the aforementioned m6807 by eMachines has been on the market for barely 2 months and it is in dire need of a BIOS update. Hopefully one will be released by eMachines (although I am a bit skeptical about this one as most of their other products don't have such low-level updates available), but if not, there are plenty of other resellers that might since this model is being rebranded by over half-dozen companies across the world. > > anyway, when i talked to thomas a short time ago, he considered going to > the lad conference, i'll go there, and concerning the schedule, you'll > be there, too ... maybe we could try to track this problem down and try > to contact the kernel mailinglist again...
