Pitch (F0) Extractor — Extract a Pitch Curve from Any Audio File
The Pitch Extractor analyzes an uploaded audio file and computes its fundamental frequency (F0) over time using the same acoustic engine as Vocametrix's clinical voice tools. The result is a pitch curve you can inspect visually and export as time-stamped data.
Open the Pitch Extractor →What you get
Upload any audio file and the tool returns a chart of pitch (Hz) over time, an average pitch value, and a downloadable CSV with one row per time point (timestamp + pitch in Hz) — ready to import into a spreadsheet or another tool.
Who it's for
Speech-language pathologists tracking vocal pitch range, singers and voice coaches reviewing pitch stability, and audio or music practitioners who need raw pitch data for further processing.
How the pitch is computed
Pitch is estimated with Praat's acoustic pitch-tracking algorithm, the same engine used across Vocametrix's clinical voice calculators, giving reproducible results across recordings.
Frequently asked questions

It's included with a Vocametrix account — sign in to upload a file and extract its pitch curve.
Can I export the pitch data?
Yes. Results can be exported as a CSV file with a timestamp and pitch (Hz) value for every analyzed time point.
What audio formats are supported?
Common audio formats such as MP3, WAV and OGG are supported.
