Limitations of AMR Files:

Audio Fidelity: AMR sacrifices some audio quality for compression efficiency, making it less suitable for music or high-fidelity audio.

Use Case Specificity: AMR is primarily intended for speech coding and may not perform well for general audio applications.

Compatibility Outside Telecom: While widely supported in telecommunications, compatibility in other software and hardware may be limited.

Conclusion:

AMR is valued for its efficiency in speech coding and widespread support in mobile telecommunications and VoIP applications.
