Here is some overview : Latest ecasound Latest libsamplerate-*HQ* aka. secret rabbit code This is important. Since there have been some issues in the past regarding standard libsamplerate, secret rabbit code and its resample-hq option in ecasound are a must. What was discovered is summarized by the following : In my case I resampled carefully ripped CD audio tracks ( 16/44.1 ) up to 24/96 because my DAC just sounds better if you feed him his designated input. This works pretty well on some songs. Example 1: The Corrs - Live unplugged - little wings or queen of holywood The results are quite impressive. Much more room, clearer heights and a much warmer live atmosphere. Example 2: George Michael - Best of - Fastlove The results are catastrophic. Clearly hearable clicks and ticks especially when there is much dynamic in the song. Could this be some effect because the original file was compressed too much during mastering ? this is quite a common problem these days. Most studios don't care about people with real high-end equipment anymore. They just stuff the music so that it will play well on radio or low tech customer gear. This is just a guess because I am no mathematician so I cannot say what kind of fluke is either in the algorithm itself or in the song causing the algorithm to bail out. Someone on the list ( I don't remember his name ) had some ideas which sounded rather profound. Please let us not give up on that issue again. cheers, Kamil -----Original Message----- From: eca...@wa... [mailto:eca...@wa...] On Behalf Of Kamil Wencel Sent: Dienstag, 25.

We ( or better ) someone in the list had some ideas about the cause but the topic just went under again. If someone finds the solution it would be really appreciated.

Subject: Re: [ecasound] Re: Resampling in realtime Hi! Thes resampling clicking problem is still there. I have to use sox, which works very well. But still I'd like to be able to use ecasound for that task as well. What is the problem there: Ecasound or libsamplerate?
