I will introduce you several MP3 to WAV cutters as follows.

Part 3. More about MP3 and WAV
At present, the MP3 and WAV formats are the two most popular audio types. We know the formats when listening to music. But many people are confused about what the MP3 or WAV formats are and the differences between them.- Small size and save space
- Acceptable fidelity
- Lossless and uncompressed data
- Use for professional work, such as broadcast
#1Description of the MP3 format
MP3 or MPEG Layer 3 is a digital audio format created by the Moving Picture Experts Group. At that time, people hoped to replicate CD-quality at a less size. In the process, it caused loss compression, which means reducing the accuracy of certain components of sound.
Pros: Cons:The partial discarding of data
#2Description of the WAV format
Waveform Audio File Format (WAVE, or WAV) is another common audio file format, which is developed by Microsoft and IBM. The format is uncompressed and retains all of the samples of an audio track, so professional users or audio experts may use it for maximum audio quality.
Pros: Cons:Large size and occupying more space
