Introducing BassMX

One of the things I have always enjoyed on my Amigas is watching demos. Close the curtains, turn off the lights, turn up the volume and enjoy.. Especially when using a Hi-Fi system with proper speakers instead of the little speakers in the monitor.

As a bit of an audiophile, the one thing that has always bothered me a little is the Amiga's perfect channel separation, also sometimes known as "drums on one speaker and the bassline on the other". This can cause the sound to be a unbalanced. I know that some people have been advocating to simply switch to mono, but that is a bridge too far for me - I'd like to keep it stereo.

So here is my solution, called "BassMX". It takes the audio from one channel, filters it so that only the low frequencies are kept and mixes that with the audio from the other channel. In short, it mixes the bass. And it does that for both channels of course.

In theory this means that the bassline and drums are now on both speakers while the locations of other instruments are unaffected. In practice it depends on the actual instruments used. While the bass drum will be centred, the high-hat will not be, for example. Similar with a slap-bass, where the slap part will still be only on the original channel but the bass sound itself will be on both channels.

I'm aware that this is not something that everybody will like, and that is fine of course. Below I have provided a couple of audio files that show the effect that BassMX has so that you can make up your own mind about it. Please note that BassMX is meant to be used with a stereo setup, this includes speakers but also earbuds and headphones. If you are using a sound system with a subwoofer then you may not hear much difference.

Initially there was a small issue with the V1.0 design, which has been fixed with the V1.1 design. Two earlier posts describe the design process. Currently I'm building a number of V1.1 modules for sale. It is taking a bit longer than anticipated since in the end this is just a hobby project that I'm doing in my spare time.

As soon as I have the BassMX modules available for sale I'll update this post. In the mean time I will be posting irregular updates on my X/Twitter profile.
