This lab exercise will introduce you to AccelDSP’s floating- to fixed-point conversion features. AccelDSP will automatically generate a fixed-point representation of a floating-point design. This process is controllable by using quantize directives.-

Music Coding  LPC-based codecs model the sound source to achieve good compression.  Works well for voice.  Terrible for music.  What if you can’t model the source?  Model the limitations of the human ear

For a file(.wave) • Find the sampling frequency and the number of bits per sample. • Re-quantize the samples using the following methods: o Linear Quantization o A-Law Companding with A=87.6 o μ-Law Companding with μ=255 •
