Gerald Gerald, do you need the files decoded into memory? You could consider doing a gstreamer based loader for the formats that are not covered by libsndfile? Then you can load mp3, aac and heck what not (e.g. loading mod files or sid songs as well). Well yes, I need the decoded audio in memory due to both the time stretching and the scratching algorithm. I also have no experience with gstreamer, thats why i didn't have it in mind. I have such code in buzztard and can point you where it is and how it works (maybe offline discussion if people are not interested in the details). Ok I'll have a look at the code.

I don't intend to mistrust you, but I remain disbelieving for now. :-) Linuxsampler is well written and reliable, but when playing intensely, it xran too here.

There are manufacturers selling dedicated PCI-cards to do VST-plugin work and free your cpu of that. Interesting, although uneligible for my laptop.. But whats the purpose of running some piece of (almost) generic software on generic platforms, when you still need specialised hardware? Being generic means (for the platform) to support a bunch of specialised applications. It doesn't bother much to buy additional hardware, in order to make the system more generic, but not being able to make it generic enough for being able to use it for a cerain specialised application. We are used to extend the systems usability through additional peripherials such as graphic-cards, audio-cards, printers That's what has made it a success. Of course you can buy dedicated audio-hardware. Its called keyboards and synths and mixers and effects (outboard). These make me lose the generality. But isn't it easier to have it all in software and carry it around on your pc/laptop/usb-stick? It absolutely would, if it gave me the same reliability. Please give us some pointers to help you improve performance on your definitely un-tuned and probably mis-configured system before making our work bad in general. I'm not making it bad. I'm even searching for a way to make it more valueable by making it more usable. I don't think my system is so badly configured - how to measure ? It's not the most recent hardware, I admit.

[LAD] dead audio projects worth resuming
Hello, I propose to collect in this thread a list of audio programs which could give a great contribute to the linux audio experience, but can't due to halted development, leaving them in a usable or less usable state. This list could then be used for developers in search of some worthy/interesting project to contribute to. I propose two programs who aren't developed anymore: rezound jack-rack I really love them and I feel sorry there's no developer taking care of them.

Re: [LAD] Has anyone ever played a plugin in realtime ... [related to:] hard realtime performance synth
2010/2/8 Paul Davis p...@linuxaudiosystems.com: not all PCs can do it. but its simply not true that PCs can't do it. Accepted. When running any 32 polyphonic hw synth, it is able to do those 32 voices anytime. When running out of the voices, something will happen (e.g. voice killing/stealing). But it won't start any noise. Something to concider Would a check for guaranteed voices be possible for a soft-synth ? That would require an extensive deterministic behavior, I think. Instead of noise generation, maybe some sort of interpolation/silence for sample values could be used, when running out of processing power.

Re: [LAD] dead audio projects worth resuming
I would say Kluppe. It is a very good looper, especially for working not with recording loops over and over, but for mixing existing loops. It would benefit hugely from adding some basic synchronization to it and time stretching (it already has a beat grid anyway). The author of it seems to be busy and not really interested in further development.
