[Bug 306861] [NEW] Sound equalisation problem with Audacious

[Arnaud Dessein]

Public bug reported:

Binary package hint: audacious

Hi,

This is NOT a report about the audacious equaliser but about the sound
audacious produces WITHOUT the equaliser.

I was doing acoustic listening tests using Audacious and FLAC files when
I have detected a difference between the equalisation of the sound
played by Audacious.

Compared to VLC or Movie Player (Ubuntu) on the same setup, same file, I
can (and my colleagues also) clearly hear a lack of low and high
frequencies.

I have tried to compensate this problem with the equaliser of Audacious
using my headphones at home. I am not an expert but the following
configuration makes the sound less different than the one I hear when I
use VLC or Movie Player :

60 Hz : + 3 dB
170 Hz : + 1 dB
6 kHz : + 1 dB

But this does not exactly compensate the problem (it does at low
frequencies I think, but not at high frequencies).

I would like someone to make a test to confirm my bug report.

I have checked that :

- I am using the same sound output module (OSS) in both cases
- The volume is the same
- There is no equalisation enabled neither on VLC nor on Audacious.

I have compared Audacious 1.5.0 and VLC 0.8.6e on Ubuntu Hardy.

Thank you

Arnaud
