ASPMA-assignment-10b.wav

Submission for assignment A10b of the excellent Audio Signal Processing For Music Applications course.

Sounds Used
I made use of the following sounds from Freesound. It was necessary to convert
them from stereo to mono for processing with the sms-tools software.

Plus the following sounds from the 'sms-tools' collection:

A small fragment from the following sample. This was the
'speech-male.wav' sample from the 2014 run of the ASPMA course.

I consciously made use of the last four sounds, above, given how
often we spent the weeks of the course listening to and analysing
them.

Transformations
I used the following transformations on these samples throughout the song:

- STFT morph between piano-phrase.wav and vignesh.wav for the
intro part, layering that with the original piano.wav for some
extra piano quality.

- Harmonic-Plus-Stochastic model (HPS) frequency scaling
transformation of vignesh.wav to make vignesh sing along with
the gentle guitar loop.

- HPS frequency scaling transformation of flute-A4.wav to make a
flute accompaniment to the gentle guitar loop.

- HPS frequency scaling and stretching transformation of speech fragment

Assembly
The results of these transformations were then cut up into sections,
duplicated and liberally sprinkled into a single mix using Audacity

Some effects were accomplished using the layering of different
sounds. For example, I layered the "singing" vignesh.wav sound I
created on top of the original sound to achieve a singing
chorus. Similarly with the speech fragment in the latter half of
the song.
