Hi Nicolas,

Here is an improved YM2149 volume table as measured by Paulo Simoes.

Please consider this for inclusion into Hatari. A quick way to try
this table is to replace hatari-1.6.2/src/includes/ym2149_fixed_vol.h
and re-compile, or maybe Hatari can have two volume tables.


Note that Hatari only uses the ST Replay table because Hatari indexes
'one less' into the Replay table when Quartet values are needed.
This allows any voice to be Quartet or Replay, independent of the others.


better late than never :) Table is now included in Hatari.


The correspondence I had with Paulo on follows:

Hi Paulo,

Could you please give me permission to use the YM2149 volume table
data in for use in Hatari.

I converted your data into C code and tested it privately. I've
listened to many chiptunes with your volume table on Hatari and
have only noticed improvements in the sound quality.

I intend to submit a C code patch (crediting you for the data)
to the Hatari developers for possible inclusion into Hatari.

Thank You,
David Savinkoff

Hello David,

You can you both tables (ST Replay and Quartet) as you wish.
SainT emulator is already using them for a long time.
The same tables were offered to STeem emulator authors but it was
after version 3.2 was available and they made no new version since.
