Seply: Turning Mixed Audio into Separate Tracks

What is Seply

Seply is an online tool that uses artificial intelligence to separate mixed audio recordings into individual tracks for each speaker. Imagine a podcast where two people are talking at the same time. Seply takes that single file and splits it so you have one clean audio file for each person. This technology goes beyond just labeling who spoke when. It actually creates separate, editable audio files that stay perfectly synchronized with the original recording. Users can upload audio or video files, and the system processes them to deliver isolated WAV files ready for editing.

Benefits

Seply offers several key advantages for audio professionals and content creators. First, it handles both automatic and manual detection. Users can let the AI guess the number of speakers or tell the tool exactly how many people are talking. Second, the tool supports many file types. It works with common audio formats like MP3, WAV, and FLAC, as well as video files like MP4 and MOV. When a video is uploaded, the tool extracts the audio without changing its quality. Third, the output is editor-ready. The resulting files are independent WAV tracks that start at the same time as the original mix. This makes it easy to mute a specific speaker, lower their volume, or remove mistakes without affecting the rest of the recording. Finally, the system can handle overlapping speech, meaning it can separate voices even when people are talking over each other, though results depend on the quality of the original recording.

Use Cases

Seply is useful in many situations where clear audio separation is needed. Podcast editors can use it to separate hosts from guests. This allows them to adjust audio levels for each person or fix errors in one voice without touching the other. Interviewers and researchers can isolate the interviewee from the interviewer to make reviewing transcripts or analyzing responses easier. Meeting organizers can convert panel discussions into separate tracks for archiving or post-production review. Video producers can also use the tool to prepare dialogue tracks before placing them back into a video editing timeline. Essentially, anyone who needs to work with mixed audio recordings can benefit from this technology.

Pricing

Seply uses a credit-based system for its services. The cost for speaker separation is one credit for every six seconds of audio started. This means a full minute of audio costs ten credits. There is a minimum charge of one credit per job. Speech-to-text services cost one credit per three minutes. Credits from monthly plans expire after 30 days, while one-time credit packs expire after 12 months.

The service offers several plan options. A free trial provides 30 credits for one-time use and lasts for 30 days. No credit card is needed for this trial. The Starter plan costs $12 per month and includes 200 credits. The Creator plan is priced at $29 per month and provides 600 credits, which is the most popular choice. The Studio plan costs $65 per month and offers 1500 credits. Users can also buy credit packs without a subscription. For example, 200 credits cost $16, 600 credits cost $39, and 1500 credits cost $89. Unused credits from these packs can be refunded within seven days of purchase.

Vibes

While specific user reviews are not detailed in the provided information, the service is designed with user convenience in mind. The interface allows users to preview the original mix alongside the isolated tracks before downloading. This feature helps ensure the separation quality meets expectations. The company also emphasizes data privacy by stating that all processing happens on private infrastructure. Original recordings and the resulting tracks are stored securely for 30 days after completion. This gives users plenty of time to download their files. The support system addresses common issues like failed jobs by automatically returning reserved credits to the user's account. This policy helps build trust by ensuring users are not charged for unsuccessful tasks.

Additional Information

Seply focuses on security and data privacy for its users. All processing is conducted on specialist infrastructure to keep data safe. The company retains original recordings and completed speaker tracks for 30 days from the time of completion. During this period, users have full access to download their files. After the media expires, only limited job metadata remains stored. Users are responsible for holding the necessary rights to upload the content they process. If a separation job fails, the system automatically returns the reserved credits to the user's original batches. These returned credits keep their original expiration dates. Refunds for unused purchased credits are available within seven days of purchase, with exceptions for duplicate charges or legal rights issues.
