BeatVisualiser vs Kauna

BeatVisualiser makes music visualiser videos for promoting tracks on YouTube, TikTok, Shorts, and Reels. Add WAV, MP3, or FLAC audio, trim it to a chosen moment, then choose from more than 30 visual styles, including Spectrum, Waveform, Vinyl, Scope, and Split. Videos can use image or video backgrounds, custom artwork, and auto-synced lyrics. Exports are downloadable MP4s in vertical 9:16 or landscape 16:9, up to 1080p 60fps. YouTube Mode allows tracks up to 10 minutes per export; short-form exports stop at 60 seconds. The free account includes all styles, 1080p 60fps output, and no watermark, but only one export of up to 15 seconds; later exports cost one credit each. Pro is $16.99 a month, and Lifetime is $149, paid once, limited to the first 150 early supporters. The site says rendering happens locally in the browser, but Safari and Firefox lack the required rendering APIs.

Kauna is a free Windows music visualizer that turns system audio into animated displays and can also capture sound from a microphone. Its visualizations include Wave, which draws frequencies as fine lines; Confetti, where colored discs change size; and Bars, described as a rainbow spectrum analyzer. The listed choices also include Burning clouds, Plasma, Sound level meter, and Triangular visualizations. Burning clouds depicts illuminated clouds, while Plasma uses smooth color transitions. Sound level meter acts as a virtual device for measuring volume in decibels. Kauna provides a sound-level sensitivity control, lets users select the sound card, and can switch visualizations automatically on a timer. The Microsoft Store lists the software as free and notes that it offers in-app purchases. The available platform information describes Kauna as desktop software for Windows.
