How do I convert FSL to AMR using this tool?

1. Upload your FSL file by clicking 'Choose File' or dragging it into the drop zone. 2. Select AMR as the output format. 3. Optionally, adjust the AMR bitrate (recommended: 12.2 kbps for speech). 4. Click 'Convert' and wait for the process to finish. 5. Download the converted AMR file. The tool streams the conversion securely and deletes the file after download.

Why should I convert FSL to AMR instead of keeping the original?

FSL is a high-fidelity, lossless audio format that preserves every detail, resulting in large files. AMR is a lossy, speech-optimized codec that shrinks file size by up to 90% while maintaining intelligible voice quality. Converting to AMR is ideal for voice memos, telephony, and mobile apps where small file size and moderate quality are acceptable.

What happens to audio quality and metadata during FSL to AMR conversion?

The conversion decodes the FSL file to uncompressed PCM, then encodes it using the AMR codec. AMR supports a maximum sample rate of 16 kHz, bit depth of 13 bits, and only mono audio. If the FSL file has a higher sample rate, stereo channels, or 24-bit depth, it will be resampled, downmixed to mono, and quantized. Metadata like album art or lyrics will be discarded, and the resulting audio will have reduced bandwidth and dynamic range compared to the original.
