# 2) Call the tool with the returned filePath values
curl -X POST 'https://api.elysiatools.com/en/api/tools/audio-wah-wah' \
-F 'audioFile=/path/to/file.ext' \
-F 'mode=auto' \
-F 'wahFreq=1.5' \
-F 'wahDepth=0.8' \
-F 'wahCenter=800' \
-F 'resonance=2' \
-F 'mix=0.6' \
-F 'outputFormat=mp3'Send a POST request with your inputs as JSON. File parameters require a separate upload first.
