Show HN: Lofi Cities – Pixel-art city nights with browser-generated lofi
Lofi Cities is a browser-based application that generates pixel-art cityscapes paired with real-time synthesized lofi music. The audio is created entirely using the Web Audio API, ensuring an endless stream of unique tracks without relying on pre-recorded samples. Users can customize the listening experience by selecting various musical styles, moods, and specific environmental sound layers.
- ▪The music is synthesized in real time using the Web Audio API, combining chord progressions, drums, and bass lines with effects like tape wobble.
- ▪The platform offers multiple musical styles including jazzhop, piano, ambient, bossa, synth, house, guitar, sad, and medieval.
- ▪Users can adjust the mood to be chill or upbeat and choose to play the full band, no drums, or chords only.
- ▪A dedicated city sounds mixer allows users to individually control the volume of environmental elements like rain, traffic, and bells.
- ▪The weather feature can change the visual scene to rain, snow, or clear nights, which dynamically updates the accompanying ambient sounds.
