Elevator Pitch

Eldoraudio Piano Audio to MIDI Converter

Piano audio to MIDI conversion done right. Upload an audio file, and we’ll transcribe the piano part into accurate, editable MIDI.

Product Description

Eldoraudio’s piano audio to MIDI converter uses a custom-trained ML model to convert piano audio recordings into accurate MIDI files. Trained specifically for piano on our own large dataset of piano recordings, it’s designed for musicians and music makers who want fast, high-quality note detection without having to pick out notes by ear. It captures nuances such as pedaling, velocity, and timing with incredible accuracy.


How It’s Innovative

The innovation here lies in the data: Eldoraudio trained its ML model on a large, self-created dataset of original piano recordings, rather than depending on existing public transcription datasets. Daniel Johnson, the founder of Eldoraudio, holds a bachelor of music degree in piano performance from BYU, and he provided the dataset through hours of his own playing. This grounds the model’s accuracy in high-quality piano performance data collected specifically for this purpose.

Most Inspiring Use Cases

Pianists recording their own improvisations, arrangements, or performances and instantly getting a MIDI version they can edit, transpose, or use as a notation starting point, without needing to already know music theory or transcription by ear.

Expansion Plans

We are using learnings from the piano model to support the newly launched guitar transcription product under the same Eldoraudio brand. We plan to continue adding more instruments and culminate in a full multi-instrument audio-to-MIDI conversion tool with unprecedented accuracy and usefulness.

Commercialization

The tool is already live and commercial. We launched paid tiers in May 2026 (Free/Flex/Pro) via Paddle as the merchant of record, using a freemium model to convert free users to paid subscribers.
