Waverider (tiatune v0.3 demo)
In the last couple of weeks, Thomas and I (well, mostly Thomas) have been working hard on a major upgrade for tiatune. The upgrade includes: - Optimized waveform generation code, increasing the sample rate from 10.4 to 13.5 kHz. - More compact player, freeing up ca. 700 bytes for music - Support...

transporter
My entry for the ZX beeper compo at DiHalt Lite 2019. Took 1st place. Made with the wtbeep engine. Recorded from ZX Spectrum 48K hardware.

HoustonTracker 2.30 Demo (TI-82)
Quick diddle made with HoustonTracker 2.30, demonstrating some of the new effects available in this version. Check out the introduction video at https://youtu.be/7TA4VeWiGVE , and grab the new version at https://github.com/utz82/HoustonTracker2/releases .

tunabit (tiatune driver test)
This nice little tune took 2nd place in the Atari 2600 music compo at Silly Venture 2k17. Made with my new TIA music driver called "tiatune", which fixes the horrible detune issues of the TIA chip. Get the driver + XM converter at https://github.com/utz82/tiatune/releases

Sleizsa Trio demo (Channel F)
After a long time, I dusted off my Fairchild F8 coding skills and made a new sound routine for the Channel F (aka VES, Grandstand, Saba Videoplay). Sleizsa Trio features 3 tone channels (one of which can play noise instead of tone), globally configurable duty cycles, and 2 interrupting click…

Phase Squeek Test (ZX Spectrum Beeper)
Testing my latest creation - an unholy abomination of a beeper engine created by mating Shiru's Phaser with zilogat0r's Squeeker. It features four operators that can either run independantly or be linked together to create more complex timbres. It also features FX tables and a load of other...
-
Squeeker Plus Test (ZX Spectrum Beeper)
Testing a new sound engine for the ZX Spectrum beeper. Squeeker Plus adds several new features to the original Squeeker by zilogat0r, including drums, duty cycle envelopes, noise, and more. It sounds quite Metal, so a Metal demo track it is! download:...
-
Beepertoy v0.1 test
Testing my latest 1-bit sound driver. Beepertoy is a meta-engine, which supports a range of different 1-bit synthesis types. It can emulate the sound of popular engines like Tritone and Octode, perform complex wavetable synthesis, and more. Sadly, the complexity of this engine means there won't…

booom (zbmod test)
ZBMOD is probably the most complex ZX Spectrum 1-bit music routine I've written so far. It mixes 3 channels of arbitrary-length PCM samples. So it's like the notorious SampleTracker used in some tracks by Mister Beep, but arguably with much improved sound. download (incl. XM converter):...
-
octode 2k16 test
Testing a new 1-bit beeper engine for the Sinclair ZX Spectrum. Octode 2k16 is basically a rewrite of Octode PWM, with better sound and frequency range. Download Octode 2k16 (includes XM converter): https://github.com/utz82/ZX-Spectrum-1-Bit-Routines/blob/master/octode2k16.zip?raw=true

HoustonTracker 2 Sound Demo (TI-82/83/83+/84+)
It's time 4 da calculator! HoustonTracker 2 is a music editor/sequencer for Texas Instruments graphing calculators. It outputs 1-bit sound through the calculator link port. HT2 features 4 voice polyphony, tons of effects, and a simple, tracker-style interface. Downloads, documentation, and more…

7days7engines Day 7: nanobeep test1
A beeper engine in 86 bytes :o This is the last installment in the 7days7engines project. Not a really serious one, but I had to fill the week somehow ;) download: https://github.com/utz82/ZX-Spectrum-1-Bit-Routines/blob/master/nanobeep.zip?raw=true (includes XM convert) source:...

7days7engines Day 6: yawp test1
Why settle for 2 channels of sample playback if you can have 3? Here's yawp, aka Yet Another Wave Player. Somewhat more rough sound quality than qaop, but hey, still better than SampleTracker :D download: https://github.com/utz82/ZX-Spectrum-1-Bit-Routines/blob/master/yawp.zip?raw=true(includes…

7days7engines Day 3: xtone test1
For day 3 of my little coding spree, I've got an engine with 2x3=6 square wave channels for you. Sound is a little more rough than in engines of the same type with less channels, but well, that's what happens if you push things. This engine also has variable pulse widths, although less…

7days7engines Day 2: quattropic - test1
A new day, a new ZX Spectrum 1-bit routine. This one features 4 square wave channels with variable duty cycle. One of the channels can also play noise instead of tone. Download (includes XM converter): https://github.com/utz82/ZX-Spectrum-1-Bit-Routines/blob/master/quattropic.zip?raw=true Source:...

7days7engines Day 1: qaop test1
This week, I'm doing a little project called 7days7engines. That means that for every day of the week, I'll release a new ZX Spectrum beeper/1-bit routine. First up is QAOP, a two-channel routine that plays short, looped PCM samples. Download (includes XM converter):...

pcmplay test1 (Dragon/Tandy CoCo)
Made a new soundroutine, this time for the Dragon 32/64 resp. Tandy Radioshack Color Computer and their 6-bit DAC. First time coding on a 6809 processor ;) The routine features 4 channels of PCM WAV playback. Samples are 4-bit, fixed length, and looped. Download, source, and XM converter at...
