Demo Two: A Saxoflute

A saxophone playing flute and a flute playing saxophone.

We first record a phrase played on a Saxophone . We chose this well known solo played by Johnny Hodges for the "swing feel" that it carries. We wanted to see if we could preserve the specific feel, articulation and phrase of this solo, when played trought another instrument.

Then we perform an analysis of this phrase using the CAST tools as in Demo 1.

Now we train a neural network using on the results of the previous analysis so that it learns the spectral behavior of the instrument. We obtain an approximation of the previous analysed phrase. This approximation is generated in real-time, using only pitch and loudness envelopes.

Here we feed the network of demo_1, that was trained on the Suling datas, with the amplitude and pitch envelopes of the saxophone phrase. We obtain "Johnny Hodges playing Suling".

Of course, we can do the reverse manipulation which consits in playing the Suling phrase through the network trained on the Saxophone: The Suling phrase on the Sax.
