Dia TTS is a browser-based stem splitter that separates an uploaded song or audio recording into six individual stems: vocals, drums, bass, guitar, piano, and other sounds. Upload a supported audio file, start the stem separation, and preview all generated tracks together in a synchronized mixer. Each stem includes its own waveform, mute control, volume control, and download button, making it easier to inspect an arrangement, isolate parts for practice, prepare material for remixing, or remove drums and other instruments from a song during playback. The tool accepts MP3, OGG, WAV, M4A, and AAC files up to 50MB and 30 minutes long. Separation quality can vary depending on the original mix, overlapping instruments, audio compression, background effects, and recording quality.

Why Use the Dia TTS Stem Splitter
Separate one mixed audio file into vocals, drums, bass, guitar, piano, and other sounds. Unlike a basic vocal remover, the Dia TTS stem separator provides multiple instrument tracks instead of only vocals and accompaniment.
Use the online audio stem splitter with MP3, OGG, WAV, M4A, or AAC files. Each upload can be up to 50MB and no longer than 30 minutes, making the tool suitable for complete songs as well as shorter music clips.
Preview all six stems together in the built-in mixer. You can mute individual tracks, adjust their volume, move through the synchronized waveforms, and compare how the song sounds with or without vocals, drums, bass, guitar, or piano.
There is no software, plugin, or VST to install. New users can sign up and use complimentary credits to try the stem splitter. Credit usage is based on the duration of the uploaded audio, and each generated MP3 stem can be downloaded separately.
How to Split a Song into Stems Online
Upload a Song or Audio File
Choose an MP3, OGG, WAV, M4A, or AAC file from your device. The file must be no larger than 50MB and no longer than 30 minutes. For more consistent stem separation, start with the highest-quality version of the audio available to you.
- โขAvoid heavily compressed or distorted recordings when possible
- โขUse a complete mix with reasonably stable volume
- โขTrim unrelated silence before uploading
- โขOnly upload audio that you own or have permission to process
Start the Stem Separation
Submit the audio for processing. The music splitter automatically analyzes the mix and creates six separate tracks: vocals, drums, bass, guitar, piano, and other. You do not need to select instruments manually. The current tool generates all six available stems for each completed request.
Preview, Adjust, and Download the Stems
When processing is complete, use the synchronized stem mixer to play the tracks together. Mute a track to hear the rest of the arrangement without it, or adjust individual volumes to focus on a specific instrument. Each generated stem can be downloaded separately as an MP3 file. Because stem separation is automated, some sounds may remain partially present in more than one track when instruments overlap in the original mix.
What Can You Do with an Music Splitter?
Use separate music stems to study an arrangement, practise individual parts, prepare remix material, or focus on specific instruments in a song.
Remixing and Arrangement Study
Download individual vocals, drum, bass, guitar, piano, and other stems for remix drafts or arrangement analysis. Compare the role each part plays in the complete mix before continuing your work in an audio editor.
Singing and Instrument Practice
Mute the vocal stem to rehearse singing over the remaining tracks, or mute drums, bass, guitar, or piano to practise that part yourself. Test different combinations without modifying the original file.
Drum and Instrument Isolation
Use the song stem splitter to separate drums from a song, inspect a bass line, study a guitar part, or focus on the piano arrangement. Results depend on how clearly each instrument is represented in the original recording.
Music Education and Transcription
Teachers, students, producers, and musicians can focus on one part of an arrangement at a time. Individual stems can make rhythm, harmony, instrumentation, and song structure easier to examine.
