Product Overview: AudioStretch
AudioStretch is a revolutionary audio and video transcription tool designed to enhance the learning, practice, and creative processes for musicians and music enthusiasts. Developed and maintained by BandLab Technologies, this app stands out as the world’s first transcription tool that allows users to modify audio and video speeds without pitch distortion.
Key Features
1. Speed and Pitch Adjustment
AudioStretch enables users to change the speed of audio and video files by up to 10 times, ranging from -10x to 10x, without altering the pitch. This feature is particularly useful for learning complex musical pieces or analyzing audio and video content in detail.
2. LiveScrub
The LiveScrub feature allows users to interact with the waveform by dragging it, causing the audio to play at the same speed as the finger’s movement. This feature also includes the ability to freeze playback at zero speed, which is helpful for working out tricky chords and solos.
3. Looping
Users can set markers to create loops of specific sections of a track, making it easier to practice and learn difficult parts repeatedly. This looping feature is flexible and user-friendly, allowing for precise control over the start and end points of the loop.
4. Pitch Transposition
AudioStretch allows for pitch transposition of up to 36 semitones, enabling users to adjust the key of a song to match their performance needs without compromising audio quality.
5. Spectrum Keyboard
The app includes a spectrum keyboard that helps identify notes, frequencies of harmonics, and overtones, making music transcription more accurate and efficient.
6. Video Support
In addition to audio files, AudioStretch supports video files, allowing users to slow down, loop, or transpose video content. This is particularly useful for musicians who want to follow along visually with their favorite artists’ videos.
7. Import and Export
Users can import audio and video files from various sources, including their music library, phone camera, and cloud storage platforms like Google Drive, Dropbox, and OneDrive. Modified tracks can be exported via email or cloud storage.
8. User Interface and Controls
The app features a responsive and easy-to-use interface with intuitive controls. Users can adjust speed and pitch by dragging left and right on the speed/pitch display, and double-tapping for instant zero-speed playback.
Additional Benefits
- Educational Access: AudioStretch offers free access to its full functionality for music educators and their students, making it a valuable tool for music education.
- Creative Applications: Beyond learning and practice, AudioStretch can be used to create engaging content, such as slow-motion videos or unique audio effects, making it a versatile tool for creative projects.
Versions
AudioStretch is available in two versions: the full version and AudioStretch Lite. The Lite version has some feature limitations, including a maximum song duration of 3 minutes, a speed range of -1.5x to 1.5x, and pitch shift of /- 3 semitones, but it provides a good introduction to the app’s capabilities before upgrading to the full version.
In summary, AudioStretch is an indispensable tool for musicians, music learners, and anyone looking to manipulate audio and video content with precision and ease, offering a wide range of features that enhance the music learning and creative process.
