Free online WAV to IMY converter

A legacy phone or ringtone editor that accepts Ericsson iMelody files may require IMY instead of WAV. WAV stores recorded audio, while IMY stores a sequence of notes, so this conversion is a transcription rather than a lossless change of audio encoding.

What the WAV format is

WAV is a container commonly used for uncompressed PCM recordings. Voice recorders, phones, audio interfaces, and editors such as Audacity often create WAV files; music and speech projects use them when preserving the recorded waveform matters.

What the IMY format is

IMY, also called iMelody, is a text-based ringtone format used by some older Ericsson and Sony Ericsson phones. It describes note pitches, timing, and ringtone playback instructions rather than storing sampled sound. Its small size suits simple monophonic ringtones, but it cannot represent the full sound of a voice, recording, or complex musical arrangement.

How to convert WAV to IMY

Online on 101convert.com

1. Open the WAV-to-IMY converter page on 101convert.com and upload the WAV file. Several files can be selected for batch conversion; the page shows the per-file size limit.
2. Start the conversion and wait for it to finish.
3. Download the resulting IMY file and test it on the intended phone or ringtone software.

Offline with desktop software

There is no faithful offline audio-to-IMY encoding: the WAV melody must first be recognized or transcribed, then represented as ringtone notes. A practical free workflow uses Audacity and a plain-text editor; it requires manual transcription.

1. Open the WAV in Audacity. For each clear, single note, select a short steady section and use Analyze → Plot Spectrum to identify its pitch; measure the note lengths from the waveform or playback.
2. Write the melody as iMelody note events using the format’s syntax, then save the text with an .imy extension. Include the required iMelody header and ending markers, and set note pitches and durations to match your transcription.
3. Test the file in software or on a handset that supports iMelody. Adjust notes and timing if the device rejects the file or plays the melody incorrectly.

For faster pitch recognition on Windows, WIDI Recognition System can attempt WAV-to-MIDI transcription. Review the resulting notes, reduce them to a single melody line if needed, and encode that line as IMY; automatic recognition can misread chords, percussion, and overlapping sounds.

Quality and compatibility

IMY does not retain WAV timbre, lyrics, background noise, or multiple simultaneous instruments. A recognizable result depends on extracting a clear melody; speech and dense mixes may not yield usable notes. Confirm that the target device supports the iMelody version and note range in the generated file.
