What you need is not some generic audio filtering package. You need simulation models for the analog filters that each MSX model has between the audio chip and the speaker output. (Whatever speakers you connect to your PC will take care of the rest.)
If you want to get a really accurate sound then I guess that it could be possible to use the spice models of the components but I think that would be overkill. In most cases a normal IIR-filter will probably do the trick but each MSX model has different filter constants.
There are some cases when the usual filter mondels just don't do it properly, for example the music in Syntax Infinity tend to make the audio filters of my NMS8250 to experience some major clipping. (Does not happen on NMS8280) This can not be emulated without also simulating the transistors in the filter.

Well, I don't aim to emulate perfectly the audio of every MSX model, since differences between all of them would be barely noticiable.

But I think that most real MSX models have a warmer sound than the currently emulated one; analog feel and warmth can be achieved by many VST plugins (including those emulating analog channel strips, valve pre-amps, etc.).

Nice ideas all... Smile

About the recording: you can already record each channel of each sound chip separately (on their native frequency) and use those recordings to make professional mixes, applying your effect filters outside of openMSX.

The scanlines at 4x scaling with default settings look very much like my Sony MSX monitor Smile

Nice to know recording of separate channels is possible... thank you.

I will try that scanlines setting (I used to connect my MSX to a Sony MSX monitor too Smile )

Thanks again for your useful tips.

I am going to buy a Dingoo A320. It is the most cheap handheld with one of the best (if not the best) MSX emulators available (openMSX). I hope it will be easy to install Dingux and openMSX.

It's not too hard, but it's also not too easy. Installing Dingux is documented on many Dingoo sites. If you need help, let us know. Installing openMSX on Dingux is documented here: http://openmsx.sourceforge.net/manual/compile.html#installstandalone
