The Distinctive Feature Of Amr Files

AMR file varies from regular audio applications because its design is especially for voice messages and voice memos on mobiles. While the audio content for non-voice content in AMR format is not that good. Find out from this article how to get the transcription of an AMR format file in the above average and high quality.

AMR File Definition and Features

An AMR (Adaptive Multi-Rate) file is a development of Ericsson company designed to compress files with the recorded speech. It is popular in cell phones and smartphones and produces an outcome file of a recorded voice. When downloading the sound files to the computer, users saw the AMR extension. These files were not of the perfect quality. Their purpose was to save the compressed speech.

Later the AMR extension improved the coding of adaptive methods where the speed of the sound stream is variable. The high quality of the speech coding allows the low weight of the received content. 

AMR relates to the narrowband speech codec with eight adjustable bit rates. Its main benefit is a wide choice of coding and decoding speeds which comes in handy during flexible switching to various modes of record depending on the environment, including the mobile network conditions. This significantly enhances the audio quality. Also, the technology offers a link adaptation method from one to eight rates with a choice of the best rate for the current environment.

This format remains popular nowadays. Users can convert it to other sound formats via appropriate software. Utility programs allow transporting AMR files to MP3, WAV, and more frequently used types.

 All operational systems support AMR files. You can play them on any digital device or computer. However, sometimes users experience problems with opening the files with the AMR extension. To play this file, they will have to install an AMR converter for transporting the source audio to another format (MP3, AAC, WMA, and more). Be careful with choosing the licensed software not to lose the quality during transportation.

The Quality of the AMR File

Recording the file with AMR extension, remember that you can not improve the quality afterward. Hence, take care of the maximal quality sound in advance:

  • turn on the microphone before making the record;
  • improve the signal chain;
  • change the outcome file format to mp3 instead of AMR.

However, you can increase the volume of the AMR file. This software you can find on the Internet. 

Here is an instruction on how to improve the volume of AMR for Windows 10:

  1. Download the chosen application or program.
  2. Add the audio files and select the needed ones.
  3. Choose the outcome format.
  4. Open output features to regulate the volume.
  5. Press the «Start» button.

If you want to save the file in the same AMR format without conversion, click «keep the original format.» 

Some programs provide the features of improving the sound quality via adjusting audio sample rate, bit rate, and channel correctness. The improvement result varies depending on the software capacity and the quality of the outsource file itself.

The Online Method of Conversion of AMR File to Text

When you need to get a text of an audio file in AMR format, you can use an online service. Usually, it’s not free. The order of conversion is not complicating:

The automatic speech recognition programs can extract the speech from the audio record regardless of its size, weight, and language. The software transcribes and translates the audio file content into the selected language with 80-85 percent accuracy. To increase the quality of the automated transcription, you need to order proofreading services. A human transcriber will work with your file, editing it to the ideal state.
