WAV Audio Quality Characteristics
WAV format supports professional audio settings that preserve the original quality of your audio:
Sample Rate
Sample rate determines how many times per second the audio is sampled. Higher sample rates capture more audio detail but result in larger file sizes. Professional audio typically uses 48kHz or 96kHz.
Supported Sample Rates: 44100, 48000, 64000, 88200, 96000, 176400, 192000 Hz
Bit Depth
Bit depth determines the dynamic range and precision of audio samples. Higher bit depths (24-bit or 32-bit) provide greater dynamic range and reduced noise floor, essential for professional audio work.
Supported Bit Depths: 16-bit, 24-bit, 32-bit (浮点)
Lossless Audio Quality
Unlike compressed formats like MP3, WAV is a lossless format that preserves every detail of the original audio. This makes it ideal for professional applications where audio quality cannot be compromised.
