Winsingad

WinSingad is software for singing training. It started life as SINGAD, which stands for "SINGing Assessment and Development", running on a BBC Micro [1] and it was designed for use in primary schools to develop and assess children's singing pitching skills.

It was later ported to the Atari range of computers [2] to take advantage of MIDI and more recently to Windows. [3] SINGAD enabled the pitching strategies used by children to be explored and compared with adult singers [4] and its use for real-time visual feedback in singing training was beneficial. [5]

WinSingad offers displays of:

• Input sound waveform against time
• Fundamental frequency against time
• Short-term spectrum
• Narrow band spectrogram
• Spectral ratio against time
• Vocal tract area
• Mean/min vocal tract area against time.

In addition, a web camera window is often placed on screen with the camera positioned at the singer's side to provide a side view to enable posture to be viewed. In effect, this is a 90 degree mirror which gives a clear indication of spine alignment.
