About this app

This app reads audio data (WAV or MP3), adjusts pitch and tempo individually, and plays and saves it (MP3 format).

It also features a function to mark playback positions, making it ideal for ear copying and English listening practice.

● Attention to Sound Quality
1. Previous pitch shifters had issues with lowering the pitch, weakening the bass and lowering the treble. This app alleviates these issues with an automatic bandwidth correction option.

2. An option has been implemented to suppress the dubiness of drum and percussion attacks, which often occurs when raising the pitch or slowing the tempo.

3. When saving as MP3, you can select the sample rate (96-320kbps). This allows you to balance storage and sound quality.

A distinctive feature is that these operations can be easily performed without using a DAW or waveform editing software.
