I'd like to share this audio improvement project I've been working and testing last weeks, recreating the audio companion for the UAV developed by Bryan, taking the Pokey output to generate a new signal. In a phrase: it's like to listen an "old sound in a new machine" instead of to listen an "old sound in an old machine". And it works. Quality sound: Time ago I was looking for an audio improvement, unfortunately there wasn't a good comparison or comments about a difference of this kind of projects with the original Atari sound, so I decided to build my own and play with it. I played changing components several times to get a clearer and smooth sound, and also increasing the power. The feeling is like listening an mp3 at 96kbps and then to listen the same song at 128kbps. You can hear some improvements in some frequencies, and it feels better, but of course it's far away from a 320kbps mp3. The main noticeable changes are with bass related sounds, now they are not lost in the background. With the sharp sounds the difference is less noticeable, but in overall I'm happy and it's a recommended improvement. (For this post I tried to make a video if we are talking about sound, but for some reason when connecting the 3.5mm cable to the camcorder, it appeared a noise not noticeable with the speakers and with the TV, so it wasn't a good comparison test to be published). Further works: Pseudo-stereo improvement: Since the 99.9% of the games and demos are mono, and the only way to convert them to stereo is to tell each developer to re-write the code, I've been searching for a way to have some kind of stereo sound. I started with splitters to divide the signal in 2 according to its frequency, but those tests were unsuccessful and with undesired results. So then, an approach to have some kind of stereo is to generate 2 signals (left-right) with different tone. And so far so good. It's not stereo but if you move around the room it's possible to hear some louder sounds to the right, and others heavier to the left, instead of to have the same mono sound to the left and to the right. Internal speaker: And the last sound-related improvement I'm testing is to install a small speaker inside the Atari, with an amplifier. Having an untouched 3rd signal with the original tone at low volume in the room, it will create a more spatial effect. It'll require more energy and it's not tested yet, but I think it will be fine, and also I will add a switch to turn it off if it becomes louder.
