Convert AMR to ADTS

Understanding AMR and ADTS file formats

AMR (Adaptive Multi-Rate) is an audio compression format optimized for speech coding, commonly used in mobile devices and voice recordings. ADTS (Audio Data Transport Stream) is a container format for AAC (Advanced Audio Coding) audio streams, often used in streaming and broadcasting applications. Converting AMR to ADTS allows for broader compatibility with media players and streaming platforms that support AAC audio.

How to convert AMR to ADTS

To convert an AMR file to ADTS, you need to transcode the audio from the AMR codec to AAC and then encapsulate it in the ADTS container. This process ensures the audio is playable on devices and software that require the ADTS format.

Recommended software for AMR to ADTS conversion

The best tool for this conversion is FFmpeg, a powerful and free command-line utility that supports a wide range of audio and video formats. FFmpeg is available for Windows, macOS, and Linux.

Steps to convert using FFmpeg

1. Download and install FFmpeg from the official website.
2. Open your terminal or command prompt.
3. Run the following command:
   ffmpeg -i input.amr -c:a aac -f adts output.aac
4. The resulting output.aac file will be in the ADTS format.

Alternative converters

Some online converters, such as Convertio or Zamzar, can also handle AMR to ADTS conversion. However, for best quality and control, FFmpeg is recommended.
