Tachyon Audio Time Stretch is a dedicated standalone application designed to extend or shorten audio files without compromising quality. It specializes exclusively in time stretching, allowing users to slow down or speed up any audio material by a factor ranging from four times slower to four times faster. The software supports a broad range of audio formats, including WAV, AIFF, AU, FLAC, OGG, OPUS, MP3, and M4A, accommodating both standard and high-resolution sampling rates up to 384 kHz. This flexibility makes it suitable for processing music, speech, or sound effects across various applications.

Quality is the primary focus of Tachyon Audio Time Stretch, leveraging advanced algorithms that maintain the original audio's stereo and spatial characteristics. It supports mono, stereo, and multi-channel configurations such as 5.1 and 7.1 surround sound, ensuring that the spatial field remains intact throughout the process. Users can work with multiple audio files simultaneously, benefiting from multi-core CPU support, although the processing is offline and requires a relatively powerful computer to achieve the best results. The software offers four different quality settings, allowing users to balance between processing speed and output fidelity.

The application provides precise control over the time stretching factor, offering several ways to specify changes including length, speed, tempo, and even video frame rates. Accuracy is high, with adjustments calculated down to a single sample and internal sub-sample precision. A built-in mini player enables users to preview the transformed audio before finalizing the process, streamlining workflow and ensuring satisfaction with the output. Tachyon Audio Time Stretch stands as a reliable tool for professionals seeking top-tier time stretching without sacrificing audio integrity.
