SRGMPitch for iPhone is a automatic music transcription app. SRGMPitch has a robust pitch detection algorithm for monophonic music files. It will also support polyphonic music file. It will allow user to load audio files from iPhones music folder. Once notes are identified, they are displayed as moving pitch graph, with audio file being played in background synchronously. Pitch detection has good frequency resolution and can show microtonality for monophonic music files (chose Audio type as Raga). For polyphonic files, chose Audio type as Song.
The notes can be viewed in MIDI/ English / Hindustani notation system.
App offers rich set of options to influence pitch detection and pitch display.
