You will certainly be able to convert Adaptive Multi-Rate Codec Files directly to MIDI Music Data Files (.amr to .midi conversion), although it seems your options are somewhat limited.
Your best bet seems to be using Awave Studio, an audio editing software capable of importing AMR codec files and exporting them in MIDI music data format.

Understanding AMR and MIDI file formats
AMR (Adaptive Multi-Rate) is an audio compression format optimized for speech coding, commonly used in mobile phone voice recordings. It stores actual audio waveforms, making it suitable for voice messages and calls.
MIDI (Musical Instrument Digital Interface) is a technical standard that describes a protocol, digital interface, and connectors for communicating musical performance data. Unlike AMR, MIDI does not contain actual audio but rather instructions for synthesizers to play specific notes and instruments.
Why convert AMR to MIDI?
Converting AMR to MIDI is useful if you want to extract musical notes or melodies from a voice or audio recording and use them in music production or as ringtones. However, since AMR contains audio data and MIDI contains note data, the conversion is not straightforward and may not always yield perfect results, especially for non-melodic speech.
How to convert AMR to MIDI
To convert AMR files to MIDI, you need software that can perform audio-to-MIDI conversion. This process involves analyzing the audio to detect pitches and rhythms, then generating a MIDI file based on that analysis.
Recommended software for AMR to MIDI conversion
- Audacity (with plugins): Audacity can import AMR files (with the FFmpeg plugin) and export audio as WAV. You can then use a tool like WIDI Recognition System or Audio to MIDI Converter to convert the WAV to MIDI.
- Bear File Converter: An online tool that allows direct AMR to MIDI conversion. Simply upload your AMR file and download the resulting MIDI.
- IntelliScore Ensemble: A commercial software that converts polyphonic audio files (including AMR, after conversion to WAV) to MIDI.
Step-by-step conversion process
- Convert your AMR file to WAV using Audacity: File → Open (select AMR), then File → Export → Export as WAV.
- Open the WAV file in a dedicated audio-to-MIDI converter like WIDI Recognition System or Bear File Converter.
- Export or download the resulting MIDI file.
Tips for best results
- Clear, monophonic audio (single melody line) yields the best MIDI conversion results.
- Background noise and complex polyphonic audio may reduce accuracy.
- Always review and edit the MIDI output in a MIDI editor for best musical results.
