How can I convert AMR to W64 step by step?

Upload your .amr file, select W64 as the output format, then click Convert. The converter decodes the AMR audio and wraps the resulting PCM data in a Sony Wave64 container. Once finished, click Download to save the .w64 file.

Why should I convert AMR to W64?

AMR is a low-bitrate, lossy codec designed for speech, making files small but lacking detail for post-production. W64 uses a Wave64 container that stores uncompressed PCM audio, so converting gives professional editors a stable, high-resolution file suitable for DAWs, critical analysis, and further processing.

What happens to the audio quality and technical attributes when converting AMR to W64?

The conversion decodes the limited AMR bitstream to its native PCM representation. For AMR-NB, that usually means 8 kHz sample rate, mono channel, and a low bitrate; these are preserved in the W64 file, not enhanced. Upsampling or adding channels inflates file size but does not restore frequencies lost during AMR encoding. No new metadata is generated.
