Strip the header

[TheAwiteb]

Our wave file is two section, the first section is the wave header (44 bytes) and second section is the original file data. And the decoding process taking long than encoding (x2 benchmarks). I think is better to strip it and rewrite the data to the output file. @Amjad50 what do you think?

My prototype of strip way with 2.7 GB

Executed in 4.79 secs fish external
usr time 3.17 secs 550.00 micros 3.17 secs
sys time 1.54 secs 353.00 micros 1.54 secs

Current way with 2.7 GB

Executed in 12.62 secs fish external
usr time 11.04 secs 472.00 micros 11.04 secs
sys time 1.54 secs 279.00 micros 1.54 secs

Nice performance boost
