Seply

Seply is an advanced online AI speaker separation tool designed to simplify the process of isolating individual voices from mixed audio and video recordings. It leverages artificial intelligence to automatically detect and split speakers into distinct, time-aligned audio tracks, eliminating the need for manual cutting and complex editing. This web-based solution supports over 30 languages and a wide array of file formats, including popular audio types like WAV, MP3, M4A, AAC, FLAC, OGG, OPUS, WMA, and Speex, as well as video formats such as MP4, AVI, MOV, MKV, and WebM, with uploads supported up to 1 GB. The core functionality of Seply revolves around transforming a single, mixed recording—be it a podcast, interview, meeting, or any multi-speaker conversation—into a set of clean, independent WAV files, one for each detected speaker. A key advantage is the time-aligned output, ensuring that all separated tracks maintain their original synchronization, making them immediately ready for professional editing workflows. Users can choose between automatic speaker detection or manually specify the number of speakers, providing flexibility for various recording scenarios. Seply is built for real-world conversations, making it an invaluable asset for content creators, researchers, and professionals. For podcast editors, it streamlines post-production by allowing independent adjustment of host and guest levels, easy removal of errors, and precise editing of each voice. Researchers and interviewers can isolate participants for in-depth analysis and speaker-specific workflows. In corporate settings, it facilitates the review and archiving of meetings and panel discussions by providing separate tracks for each contributor. Video producers benefit from independent dialogue tracks that can be seamlessly integrated back into their video editing timelines, enhancing overall production quality. Unlike speaker diarization, which merely labels who spoke when, Seply goes a step further by generating actual, editable audio tracks for each speaker. This distinction is crucial for tasks requiring manipulation, enhancement, or reuse of individual voices. The platform ensures private and secure processing, with results and original recordings retained for 30 days. Seply operates on a clear credit-based pricing model, allowing users to see estimated costs before processing begins, with options for monthly plans or one-time credit purchases. This comprehensive approach makes Seply a powerful and user-friendly solution for anyone needing to cleanly separate voices from complex audio environments.
