Transcoding a Picture in the Spectrogram

You can transcode pictures in the spectrogram and thereby define a watermark. The transcoding is audible in the audio file.

1. In the Audio Editor, select the Spectrum tab.
2. In the Selection section, select the Rectangle Selection tool.
3. In the Spectrogram or in the Wavelet display, define the region in which you want to apply the picture.
   Note

   It is recommended to display the spectrum with a linear scale, because the text scaling is frequency-linear based. You can activate the linear frequency scale in the Spectrogram Options dialog.

4. Specify the Gain level.
5. In the Processing section, open the Processing Algorithm menu and select Transcode Picture.
6. In the File Explorer/macOS Finder, select the picture that you want to transcode and click Open.
7. Click Apply.

Result

The picture is written into the spectrogram.
