[Audio-engine-dev] Suggestions to completely Free the JavaSound implementation

[Peter Salomonsen]

Hi,

As for hickups - this again relies of the audio driver - where Frinika
provides a realtime priority driver on Linux - making Gervill run entirely
without hickups on my 2 year old amd64 single core computer (800 MHz in
powersave mode). Latency about 11 ms.

My experience with softsynths in java is very good in fact - first versions
of Frinika, used to run on 700 MHz Pentium III - and no glitches or problems
whatsoever. Could be used for live performance. Benchmarks also show that
number crunching in Java is very fast.

For the future - Just In Time (JIT) compiled code will be better since there
are a variety of configurations. Precompiled C code for i.e. i386 will not
run optimal on todays dual core processors, while code in Java or .Net will
(since optimization is done on the fly).

And the fact that it is the Java language - we're talking about a soft synth
for java - why shouldn't it be written in Java..

See Gervill in action using the latest version of Frinika:

This is a live recording ...

cheers,

Peter
