I've almost finished (bass traps and other
acoustic treatment remains)
building my little home studio and of course: every software is all Linux.
The rooms small size (3.00m x 3.40m = 10.2 m²) makes it lesser than ideal
when it comes to acoustics but the room's sound is great so I don't really
worry to much about it under the circumstances.
When I'm done with bass traps and foam materials, then it's time for the
final corrections as far as it goes. I do have a full two channel 1/3
octave EQ (Phonics PEQ 3600 2 x 31) that can do very much, how can Linux
help me to do the right sound here?
Help one: japa
Its a frequency analyzer and can output white and pink noise. It can help you
set your EQ correctly.
But eq'ing isn't all:
Ken Restivo used Jconv when mixing and emulating
different rooms and
situations. And it sounds to me as a very good solution and leaves two
questions:
1: How do one measure and flattern out the room'm and monitor's
frequency curve with Linux. Do one use pink noise or a sinus
sweep or perhaps both? I have two mikes which is probably good
enough for this, but how do I do it and which SW?
To really flatten and optimize the room-response electronically you will have
to record the impulse response of your room (for each speaker) and use drc to
compute a correction function in time and frequency domain. Then you can use
that pulses with jconvolver to get a better room. I do that at my home and its
really great, even though my speakers already where great.
Here is a catch: with digital room correction you will have to undo some of
your room optimizations. But the details are in the very good drc-manual.
2: How do I emulate "the perfect" studio and
other situations with
the help of Jconv?
Once your room is optimized, you can use any additional impulse response to
put your room into another acoustical environment...
Have fun,
Arnold
