AAC enable decode to 24/32/float


Recommended Posts

AAC internally uses floatingpoint math, so it would be great if Poweramp had the ability to decode it to a high resolution format. This could be a setting or automatic by matching the output device's format.

The screenshot is of a 24bit/96kHz source converted to AAC using ffmpeg.

Poweramp uses float 32/64 internally for all DSP processing anyway, at whatever sampling frequency you have defined in the Audio=>Output menu. There is currently no output-follows-source option, so you'd need to define the processing/output frequency as the highest you will need for any of your files (and that your output device supports) and allow lower resolution content to be automatically upsampled.

I was primarily referring to the 16bit in 'AAC LC 16bit'. I read it as Poweramp decodes the AAC to 16bit before it passes it to internal DSP where it gets upsampled again.

The second point can be ignored because, as you say, Poweramp uses high internal precision anyway and it is better to preserve the source resolution as far as possible.
