Zeddy audio playing now a reality!

[Moggy]

Having downloaded Adam's juke box player for use via the AY chips B port I immediately sent off for a ladder DAC board to have a go at making it work.
I then noticed two things, one I had a box of the same value resistors that the board uses and also the the spand has all the B port holes nicely lined up for soldering!

Short version.

A bunch of soldered resistors later I'm now listening to some lovely music as clear as a bell. It seems that as well as MIDI the humble little zeddy can now stream audio from the SD card at a good rate and a good quality by the standards of the machine.

So thanks Adam I'm one very happy cat!

Now were's my copy of Dark Side Of The Moon?

Not bad for a micro that’s “supposed” to be silent

Doing things it never even dreamed of...

Yeah late to the party but... This project seemed good enough to dig the old zeddy out and whip up a ladder DAC...

anyhow Moggy showed me how to convert music files into the format needed for the player and i'm sitting here listening to ghostbusters on repeat

i have enough zeddies that i can dedicate one for a jukebox...

Thanks Moggy and Adam and the MIGHTY SIIRMORRIS

P.S.. i may be gone a while take a nimute to convert these track and i have..... lots


edit reason :- because i'm a silly billy.

Andy’s returned and landed on Earth (apparently).

I knew I'd get your mojo back if I dangled a suitable carrot.

Which compressor are you using? Not Audacity's built in one I hope as it's junk!

You forgot to thank Charlie as well as it was a three way project !!

I've sold your TS1500 to cover the cost of the tea and Biccies I had to get in for you, glad I didn't have to buy the fish and chips!!

Apart from that I've sent you an e-mail !

[nollkolltroll]

Wow, another user! This makes me really glad

[Moggy]

Just a thought Adam.

Would it be possible to use the A-port in some way connected to another DAC for stereo? Audacity can save a stereo file as 2 split mono's so left channel to one DAC right channel to the other. Or is speed and timing an issue, I ask in all ignorance?

[nollkolltroll]

Moggy, stereo is indeed possible but at reduced samplerate. I don't remember if shuffling data from the card was a bottleneck or not.

[Moggy]

Thanks for that Adam.

Best leave it as mono then as the quality is more than good enough.
