Created by SH

45 Mix Trackr was created by SH, a New York–based designer who DJs vinyl as a hobby. While recording and editing mixes, SH realized how time-consuming it was to manually identify tracks, organize metadata, and prepare everything for publishing.

What started as a personal solution to speed up this workflow turned into a tool designed to help other DJs and creators do the same — faster and easier.

A free tool built for DJs, music producers, and content creators who need to identify every song in a mix — fast.

Whether you're uploading a recorded DJ set to YouTube, creating a tracklist for your podcast, or organizing your archive of old mixes, 45 Mix Trackr does the heavy lifting. Just upload your audio or video file and get back a complete tracklist with song titles, artists, and album artwork — all in one click.

What It Does

  • Identifies songs in audio and video mixes using audio fingerprinting
  • Returns song title, artist name, and album cover for each recognized track
  • Generates a downloadable SRT subtitle file for use in DaVinci Resolve, Premiere Pro, and other editors
  • Packages all album covers into a single ZIP file for easy download
  • Supports MP3, MP4, WAV, M4A, and AAC files up to 500 MB

How It Works

Your uploaded file is split into 30-second audio segments. Each segment is sent to ACRCloud — a leading audio fingerprinting platform trusted by broadcasters and streaming services worldwide — for identification. Results are returned in real time as each segment is processed.

Album artwork is sourced from Spotify metadata (via ACRCloud) and the Apple iTunes Search API. Files are processed on secure servers and deleted automatically after your session ends.

Who It's For

  • DJs who want to publish tracklists for their recorded sets
  • Video editors who need timestamped subtitles showing song names
  • Podcast creators who play background music and need attribution
  • Music lovers who want to identify songs from a recorded mix
