Alion Tech Studio Audiogram Maker vs Flowjin

Alion Tech Studio Audiogram Maker is a free web tool that turns audio clips into waveform videos with sound. It accepts MP3, WAV, M4A, OGG, and FLAC files. You can trim a clip, add a title, subtitle, cover art, and optional background image, then customize waveform and background styles. Export layouts include square 1080×1080, vertical 1080×1920, portrait 1080×1350, and wide 1920×1080. Chrome, Edge, and Firefox produce WebM files with Opus audio, while Safari produces MP4. Clips can be up to three minutes, and exporting takes about as long as the clip because recording occurs in real time. Audio is decoded, analyzed, and recorded in the browser; the page says files are not sent to a server. No account is required, and preferences remain in browser storage until site data is cleared. The free plan costs nothing, has no watermark or upload, and allows unlimited exports.

Flowjin turns branded long videos and audio into captioned clips and drafts social copy for LinkedIn, YouTube and X. Its AI identifies moments to share and automatically drafts 6–12 clips.
