Hi, I hope this is the right section.
I've got a notebook with a creative soundblaster audigy 2 NX (usb) and 2.0 Edifier R1600plus.
I'm trying to reach the best audio quality with foobar. Can you help me?
I've installed asio4all and then also foobar bassexciter to add windows media player trubass and wow effects on foobar but I don't know how to configurate them.
I want to take out the max from my speaker.
Thank you!

For playing a MP3 file, the chain of audio is as follows:

MP3 file ---> media player ---> driver --> soundcard --> cable --> speakers

On the digital side of this, audio can be treated as stream of numbers (samples), on the analog side audio is represented in voltages.
A media player like foobar opens the file and decodes it into samples. These samples are then simply fed into the buffer of the soundcard driver.
That's for the digital part of it. Now the soundcard transforms the samples into voltages which are send out on the output port, and via the cable to the speaker. The speaker than again transforms these voltages into vibrations of the air - which we can hear as sound.

The only serious way to measure audio quality is to compare of what is played back with what was recorded.

When recording audio, the most important factors are the microphone and the room.
Accordingly on the playback side the most important factors are the speakers and the room.

So if you'd really want to improve audio quality, the best thing to do is to invest into good speakers.

There's very little you can do on the digital side.

- The decoder has negligible influence. Every decoder should produce the same output from the same file within some rounding tolerance.

- The only transformation the media player makes is to scale the samples with the volume control. For best audio quality it should be clear to leave the volume control at the maximum, because if you scale it you will loose some (however minor) degree of numerical precision. Always scale on the far end of the chain if possible.

But wait... what about super-mega-bass-enhancers, equalizers, etc?
One word: DON'T
.. Unless you'd like to accurately measure the frequency response of your system. And even than you have to consider that using an equalizer will always distort your audio in some way (for example increasing the noise floor).

- The driver shouldn't do anything to the numbers except from handling them to the soundcard. So using ASIO instead of direct x drivers will change nothing - the numbers are the same.

- Concerning shielding of the motherboard: Yes, it's an issue on many laptops. There are some exceptions, the Mac Book/Mac Book Pros are shielded, as well is my Elitebook workstation and as far as I know Lenovo Thinkpads.
Will an external soundcard help? Depends...
Usually it doesn't! This is because the soundcard is connected via Firewire (or USB) to the motherboard - so the noise might propagate to the external soundcard.
The only thing that really helps is to get rid of the grounding by covering the ground pins with tape or prepare a 2-pole cable to fit into the 3-pole socket of your laptop's AC adapter.
