How do I convert F32 to AMR?

Step-by-step: Upload F32 (32-bit float WAV) file, select settings (AMR-NB or AMR-WB, bitrate), click convert, download the resulting AMR. The tool automatically handles sample rate conversion and channel adjustments during the process.

Why should I convert F32 to AMR?

F32 is a high-resolution 32-bit float PCM format used in professional recording and editing; it preserves full dynamic range but has large file sizes. AMR is a compressed speech codec (bitrates 4.75–12.2 kbps) designed to shrink voice files while maintaining intelligibility, making it perfect for voicemail systems, mobile messaging, and embedded applications where storage and bandwidth are limited.

What happens to audio quality and metadata when converting F32 to AMR?

The converter downsamples the high-fidelity floating-point samples to the AMR codec's fixed-point encoded bitstream, which uses perceptual audio coding optimized for speech. This reduces file size dramatically but discards high-frequency content above 4 kHz (narrowband) or 8 kHz (wideband) and applies lossy compression. Metadata like tags are not preserved unless explicitly copied; we keep sample rate and channel settings based on your selection.
