96 kHz Hi-Res Double the standard quality. Tests the resampling engine of the playback device. 30 MB Download

Technical Specs: WAV

  • LPCM Data: WAV stores audio as Linear Pulse Code Modulation. It’s a raw grid of values (amplitude over time). No decompression is needed to play it.
  • File Size Limit: Standard WAV files cannot exceed 4GB due to a 32-bit header limitation. Larger files use the RF64 extension.
  • MIME Type: audio/wav or audio/x-wav.

Frequently Asked Questions

Why are WAV files so much bigger than MP3?
WAV keeps every single detail of the recording (Lossless). It takes snapshots of the sound 44,100 times per second. MP3 throws away sounds that are “masked” by louder sounds to save space. A WAV is typically 10x larger than an MP3.
Do web browsers support WAV?
Yes. All modern browsers (Chrome, Firefox, Safari) play WAV files natively. However, developers usually prefer MP3 or AAC for background music to save bandwidth, keeping WAV for short UI sound effects (clicks, alerts) where latency matters more than size.

How to edit WAV files?

Since WAV is uncompressed, it’s the best format for editing before exporting to MP3/AAC.

  • Audacity: The #1 free tool. Perfect for trimming, normalizing, and converting WAV files.
  • Adobe Audition: Professional tool for mixing multi-channel WAVs (like the 5.1 sample above).
  • VLC: Useful for playing “Float 32-bit” or multi-channel WAVs that Windows Media Player can’t handle.

Developer’s Corner: Parsing WAV

Python has a built-in wave library. You don’t need external tools to read the header properties (Sample Rate, Channels).

# Python: Read WAV Metadata (Native)
import wavewith wave.open(‘audio.wav’, ‘rb’) as f:
params = f.getparams()
print(f“Channels: {params.nchannels}”)
print(f“Sample Rate: {params.framerate} Hz”)
print(f“Duration: {params.nframes / params.framerate:.2f} sec”)
