Guides
Short, practical write-ups on the things the tools do — what the numbers mean, which setting matters, and the mistakes that are easy to make once and confusing forever. Every one is free to read and links to the tool it describes.
- How to make a beat switchWhat a beat switch actually is, where to put it, and how to line two songs up when their tempos disagree.
- Find the key and BPM of any songThree ways to get a track's key and tempo, why estimators disagree about half and double time, and how to tell which answer is right.
- The Camelot wheel and harmonic mixingHow the 24 codes work, which pairs mix cleanly, and how to plan a set that never clashes in key.
- How to make a slowed + reverb editThe speed, pitch, and reverb settings behind the sound, and why slowing a track drops its pitch with it.
- What is LUFS, and streaming loudnessWhat LUFS measures, the targets Spotify and Apple Music normalize to, and why a louder master is not a louder stream.
- How to make a ringtoneTrim a song to the right length, fade it properly, and save it in a format your phone accepts.
- How to convert a YouTube link to MP3Which bitrate to pick, why 320 kbps is headroom rather than extra detail, MP3 vs WAV vs MP4, and where the line is on personal use.
- How to compress a video for DiscordWhat the upload limit is, why it applies per file, the bitrate math behind every target size, and when 10 MB is simply not reachable.
