WAV Waveform - Export a Transparent PNG
Render the complete min/max waveform of a 16-bit PCM WAV, showing channels, duration and sample peak. No LUFS or true-peak claim.
The transparent PNG shows the full sample extent and the combined channel min/max envelope. Sample peak is not true peak or integrated LUFS. Compressed audio is outside this first qualified adapter. Stereo and higher sample-rate files reach the 64 MiB byte limit sooner; for example, 16-bit 48 kHz stereo is limited to about 5 minutes 49 seconds, while mono at the same rate can reach the 10-minute duration limit.
