Welcome to NoteHound

NoteHound is a music practice and transcription app built for musicians who learn by ear. Load any audio file, slow it down without changing pitch, loop difficult passages, and transcribe melodies using the piano roll or guitar tab editor.

Who is NoteHound for?

NoteHound is designed for any musician who learns songs by listening — guitarists, bassists, pianists, students, and transcribers.

What can you do?

• Slow down audio from 0.1x to 3.0x without changing pitch (full range requires Pro; Free supports 0.5x – 1.5x)
• Loop sections with precise A-B markers
• Transcribe notes using the piano roll or guitar tab editor with 28 articulation annotations
• Play along on the built-in keyboard with 9 synth sounds
• Export your work as MIDI, PDF, MusicXML, or plain text

Supported Audio Formats

NoteHound supports all audio formats handled by iOS: WAV, AIFF, MP3, M4A, AAC, FLAC, OGG, and more. For the best quality, use lossless or high-bitrate files.
