PSOFT Audio Player 1.12

The audio manipulation capabilities presented by this music player are impressive, yielding results that feel remarkably authentic. In my personal assessment, the ability to adjust both the key and speed of music independently stands out, as does the effectiveness of extracting or removing certain sounds without compromising overall audio quality.

This application is particularly beneficial for a variety of users, including:

• Musical instrument practitioners.
• Karaoke track creators.
• Those engaged in musical transcription.
• Dancers preparing audio tracks for practice.
• Individuals learning foreign languages through podcasts.
• Listeners seeking efficient information gathering from podcast content.
• Users who require comfortable audio-typing solutions.

Often, traditional audio equipment suffers from significant audio degradation when making substantial adjustments to key and playing speed. However, utilizing the innovative “PhaseGear” technology within this app minimizes such degradation remarkably. The resulting audio maintains a natural sound profile that is quite surprising.

Main Features:

• Change playing speed [Time stretch]: Adjust speed without affecting the key (ranging from 0.00x to 4.00x).
• Change key [Pitch shift]: Modify the key independently of speed (up to ±24.00 semitones).
• Change voice [Formant]: Alter voice characteristics (±24.00), with a correction feature to minimize unintended voice changes from key adjustments.
• Remove/extract sounds [Audio masking]: Visualize and manipulate specific sounds within an audio spectrum, leveraging new technology to maintain high quality without unwanted rhythmic mixing. Note: Desired results may vary based on the musical structure.
• Analyze audio and display chords [Musical scale analysis]: Automatically analyze music during playback and display corresponding musical scales on a keyboard, along with inferred chords on-screen.
• Output modified audio [Export (*Add-on)]: Export modified audio files for use on different devices. This feature requires an additional purchase.
