FAQ
Frequently Asked Questions
Does the website upload my MP3 file?
No. The MP3 file is selected from your device and played by your browser. The site does not upload your audio file, store it, or send it to a server.
Why does the player only ask for MP3 files?
MP3 is widely supported across browsers and devices. Keeping the first version focused on MP3 makes the tool simpler and more predictable for learners who want a quick practice session.
What is a good A/B loop length?
For listening practice, ten to twenty seconds is a good starting point. For pronunciation or music practice, a shorter loop of three to eight seconds can work better.
Can I use the tool on mobile?
Yes, as long as your browser can open local audio files. The interface is responsive, but longer practice sessions are usually easier on a laptop or tablet because the timeline is easier to control.
Why are the buttons disabled before I choose a file?
The player needs an audio file before it can set A and B points, seek through the timeline, or change playback speed. Once an MP3 is loaded, the controls become available.
