016 - Floating-Point Audio Processing with FPGAs. In this post we will take our first steps into the world of floating-point audio processing with FPGAs by converting our fixed-point audio samples to floating point and performing a basic delay operation. Most processing in FPGA designs is done using fixed-point number representation, and most ...

Integer vs Floating Point: Which is Better?

https://forum.bottlehead.com/index.php?topic=2713.0

It was suggested that I start a new thread to discuss the topic of "Integer Audio vs Floating Point Audio." For starters, fixed point is the same as an integer (this will help in reading the article). "A value of a fixed-point data type is essentially an integer that is scaled by a specific factor determined by the type. For example, the value ...

48-BIT INTEGER PROCESSING BEATS 32-BIT FLOATING …

floating-point DSP implementations include an ALU with 32-bits of mantissa for somewhat better resolution in the multiply-accumulate operation that is at the core of so many algorithms in professional audio processing. Indeed, when we compare 32-bit floating point with 24-bit integer, there is some advantage to the floating-point.

Danger in Floating-Point-to-Integer Conversion

https://www.cs.cmu.edu/~rbd/papers/cmj-float-to-int.html

Most audio programs convert floating point samples to integer samples and write them to a file or an audio output device. I will assume that ‘‘correct’’ behavior is …

bit depth - How come floating point audio doesn't clip ...

https://sound.stackexchange.com/questions/37360/how-come-floating-point-audio-doesnt-clip

Floating point audio. With floating point numbers the whole situation changes: since the format is composed of a number (the significant) and an exponent that scales that number, the range is not fixed the same way as with the integer formats - we can "move" the range and practical utilization of the bits that in the end make up the physical ...

Floating point for FPGA-1 - Cornell University

add, multiply, negate, and because audio and video codecs require fixed point integers, you need to convert integer-to-float and float-to-integer. Floating point implementation I decided to use 18-bit numbers because 18 bits is a native width for Altera’s
