How do I convert a UL file to WMA using LetsConvert?

Upload your UL (µ-law) file to LetsConvert, choose WMA as the output format, select your preferred sample rate (8kHz is default for UL), click 'Convert', and download the result. UL files are raw codec streams, so our converter decodes them and re-encodes to WMA in one step.

Why should I convert UL to WMA instead of keeping it as UL?

UL (µ-law) is a telephony codec producing very large, uncompressed 8-bit files with low fidelity. WMA offers up to 70% smaller file sizes, supports 16-bit audio, and is natively compatible with Windows Media Player, making UL recordings easier to store, edit, and share.

How does the UL to WMA conversion handle sample rate and bit depth?

Our converter preserves the original sample rate (usually 8kHz) and converts the 8-bit µ-law data to 16-bit PCM before encoding to WMA. Since UL is lossy companding, there is no quality gain, but all original audio data is retained without resampling. If you upscale to 16-bit/44.1kHz, you'll get a larger file with no added fidelity; we recommend keeping the native settings.
