4. Results¶

Various .wav recorded audios were available for decoding. Results are presented for each recorded signal with 2080 pixels width and for 120 lines/min and an approximate 10 minute signal, a height of 1200 lines (which translates to 1200 pixels). However some audio files are less than 10 minutes resulting to smaller heights.

Figure 4.3 shows the effect of decoding a noisy recorded signal, resulting from the difficulty in detecting the maximums in the correlation with the synch wave form.
