Sorry to respond to this belatedly, but I had to weigh in.

Personally, I would take fixed point over floating point any day. In audio, there's no need for extended dynamic range afforded by exponent. The range of interest is only 0dBFS and down. 32b float wastes 8b on exponent, extending dynamic range by 256dB over the 144dB afforded by mantissa.
There are many, arguably common, DSP applications, usually employing transform mathematics, where extended floating point dynamic range is beneficial for maintenance of precision.
