Slow and low quality output

richardpl

Just tried command line tool. Trivial conversion from 44100 -> 48000 -> 44100. Produces huge differences. (Is it wrong synchronization I dunno.) and manages barely 3x real time processing.

Hey thanks. Can you provide more info, though ? - what was the source file (size etc) - send me a copy if possible - what OS and compile options etc - can you show the commandline output ? Cheers ps, I get about 24x realtime on my old i7 laptop, so 3x sounds like something is definitely going wrong. >resampler -i "D:\_music\wav\Unknown Artist\Unknown Title\01 - Track01.wav" -o test.wav -r 48000 2.1.0 64-bit version Input file: D:\_music\wav\Unknown Artist\Unknown Title\01 - Track01.wav Output file: test.wav input bit format: 16 source file channels: 2 input sample rate: 44100 output sample rate: 48000 Scanning input file for peaks ...Done Peak input sample: 0.502472 (-5.977764 dBFS) at 0:0:3.062721 LPF transition frequency: 20045.45 Hz (90.91 %) Conversion ratio: 1.088435 (160:147) Writing Metadata Converting (multi-stage) ...
