As for me, GStreamer is a good and free MP4 to WAV converter. It is an open-source multimedia framework that enables the construction of graphs of media-handling components. It's used for:

• Audio and video playback
• Recording
• Streaming
• Format conversion (like MP4 to WAV)
• Filtering and effects processing

GStreamer uses a pipeline-based architecture where you connect different elements (sources, filters, sinks, etc.) to process media data.

Here's how to convert MP4 to WAV format using GStreamer:

gst-launch-1.0 filesrc location=input.mp4, format=S16LE, rate=44100,channels=2,  location=output.wav

Breakdown of the Pipeline:

• filesrc location=input.mp4 - Reads the input MP4 file
• ! decodebin - Automatically detects and decodes the content
• ! audioconvert - Converts audio to a standard format
• ! audioresample - Resamples audio if needed
• ! audio/x-raw,format=S16LE,rate=44100,channels=2 - Sets output format to 16-bit signed PCM, 44.1kHz, stereo
• ! wavenc - Encodes to WAV format
• ! filesink location=output.wav - Writes the output to a file

XMedia Recode is a free, Windows-only video & audio transcoder created by German developer Sebastian Dörfler. Powered by an up-to-date backend, it can import almost any media file and export to 500-plus formats such as MP4, MKV, MP3, FLAC, and WAV. The free mp4 to wav converter supports hardware-accelerated encoding, batch queues, and per-track copy/convert controls, all in a single-window interface that stays 100 % ad-free.

1. Load your MP4

Click Open File (or drag-and-drop) and make sure the clip appears in the job list.

2. Choose an audio-only profile

Go to the Format tab.

Set Profile → Custom and Format → Wave / Wave (this automatically selects PCM inside a .wav container).

3. Disable the video stream

Switch to the Video tab and set Mode to Copy or Disable so only audio is processed—this keeps the encode fast and avoids creating a blank video track.

4. Tweak audio parameters (optional)

In the Audio tab you can pick sample rate (16–48 kHz), channel layout (Mono/Stereo), and bitrate mode; leave defaults for a bit-perfect PCM rip.

5. Queue & encode

Click Add to queue, verify the output folder at the bottom of the window, then press Encode. The progress bar will tick up and your .wav file appears in the chosen directory.

Tip: XMedia Recode’s queue lets you batch convert mp4 to wav in one pass—ideal for podcast or lecture archives.
