About Song Speed Changer

Song Speed Changer is a simple and effective tool that lets you adjust the playback speed of audio files stored on your device. You can slow things down for clarity or speed them up for energy — all in just a few taps.

💡 How it works:

1. Select an audio file from your device
2. Choose a playback speed – from slow (0.25x) to fast (4.0x)
3. Tap "Save Audio" – your file will be processed and saved in M4A format
4. Play your edited audio using the built-in audio player

✅ Features:

1. Supports common audio formats like MP3, M4A, WAV, OGG.
2. Automatically saves processed files to your device
3. Warns you if an audio file cannot be processed

⚠️ Note: Some audio formats or damaged files may not be supported. If an issue is detected, the app will let you know so you can try a different file.
