Converting MP3 to WAV: what to know
MP3 is converted to WAV when a program requires it: many video editors, audio tools, phone systems and voice-over devices accept only WAV.
The quality won't improve: WAV keeps the sound exactly as it was in the MP3, only uncompressed. The file becomes about 4–11 times larger, depending on the MP3 bitrate.
If a program needs specific parameters, such as mono at 8000 or 16000 Hz for telephony, set the channels and sample rate in the settings.
MP3 or WAV: which to choose?
MP3 (MPEG-1 Audio Layer III)
MP3 is the most universal audio format: compact files that play anywhere.
Best for music, podcasts and audiobooks on any device.
WAV (Waveform Audio File Format)
WAV stores uncompressed audio: maximum quality, but about 10 MB per minute.
Best for recording, editing and working in audio editors.
What happens when converting MP3 to WAV
Converting to WAV will not restore the quality lost in MP3 - the file will only get bigger. It makes sense when a program requires WAV.
Trim the fragment, convert stereo to mono or change the sample rate.
MP3 files up to 512 MB are supported; the actual limit also depends on the free memory of your device.
