Fix42 Audiogram Maker vs Flowjin

Fix42 Audiogram Maker is a free web tool that converts an audio clip into a waveform video for social-media sharing. It accepts MP3, WAV, M4A, and AAC files, and lets you select the audiogram’s visual style and colors. Optional cover artwork can be included. The service exports H.264 MP4 video with AAC audio at 30 fps in square 1080×1080, vertical 1080×1920, or landscape 1920×1080 formats. Rendering takes place on the server with FFmpeg. You can use the tool without an account or email address, and downloaded videos contain no watermark or branding. Uploads are limited to 50MB and 10 minutes; the rendered video uses only the first 120 seconds. Audio and cover images travel over HTTPS, are used for rendering, and are deleted afterward. Fix42 describes podcast quotes, interview highlights, and music teasers as use cases.

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. The editor provides smart cropping, speaker tracking, captions, titles, B-roll, and tools to trim or extend clips. Users can upload audio or video or import media links, including from YouTube, Apple Podcasts, Google Drive and Vimeo.

Flowjin can generate titles, descriptions, hashtags and calls to action. The pricing FAQ lists English, Spanish, Portuguese, French, Dutch, German and Italian as supported media languages. The homepage describes scheduling through a shared calendar, while pricing says social publishing is coming soon. A free plan is listed at free, with a one-time 60-minute credit and projects that expire after five days. Starter is $19 a month and Creator is $29 a month; their project retention limits differ. Flowjin presents the service for founders and CEOs, marketing leads, social media managers and agencies.
