Nicer sounding fugues

Stéphane Rollandin
> Patrick Rein uploaded a new version of Sound to project The Trunk:

> ==================== Summary ====================

> Fixed an important issue about the naming of the Bach fugue...

Currently if you do

        PluckedSound bachFugue play
        FMSound bachFugue play

in a 5.1 or 6.0 image you will get not-so beautiful melodies, featuring
glitches and bad reverb effects.

I did a few tweaks to FMSound, PluckedSound and AbstractSound for muO
that improve things a bit IMO. These changes are completely independent
from muO code per se, so they could be ported to trunk.

To try them, download the 6.0 image at
http://www.zogotounga.net/comp/squeak/nicer%20fugues.zip

and evaluate the above lines of code in that image.

What do you think ?

​Exept for the changed panning I don't notice a difference ... then again I'm not a​ musician so if you think this makes it better, I'd say go for it.

Hmm.. that's strange.

The difference is very noticeable on my system: in a vintage image the
reverb (which by default is on) adds shaker-like echoes to each
PluckedSound note. As for the FMSound, there is a lot of sizzling in the
louder notes at the end of the fugue.

Did you listen with headphones ?

I loaded your AbstractSound, FMSound, and PluckedSound classes into a Squeak 4.6
image because I am using Linux and run an interpreter VM to get pulse audio
output. The changes seem to be all in AbstractSound (I only loaded the other
two because they were mentioned in a previous post).

With the changes, I think that I hear less brightness and treble, although also
a lower volume setting. With FMSound, there is much less distortion with your
changes, although some of this may be just due to the volume setting. I think
that I somewhat prefer the brightness of the sound before the changes, but I
definitely like the reduced distortion.

I am not a good judge of this, and I am only using a Linux laptop with headphones.
I suspect that the sound quality may vary a lot depending on the operating
system and sound card, so hopefully a few other people can try this and
give their observations.

Hoi Stef--

> What do you think?

     Yes, nicer. The reverb didn't work so well on the plucked strings,
and the FM sounds warmer now.


     thanks!

That would definitely be very interesting. It's a surprise to me that
the OS may be so critical in the quality of the sound output. I'm on
Win8.1, with a decent sound card.

Reverb is turned of by default in newer images AFAIK

Best,
