    Possible Feature for REW

    One of the problems we have when evaluating very nonlinear circuits such as sigma delta dacs is that modulator behavior is not always easily understood from looking at typical FFT measurements. For instance, its possible for a dac to reproduce a periodic-steady-state (PSS) sine wave in a way...

    Hearing loss and DACs

    A properly designed dac using galvanically isolated Asynchronous USB is as good as it gets. Bit perfect, extremely low phase noise, etc. To get the same performance with SPDIF is more difficult, it requires FIFO buffering at the dac end. Native DSD is not possible. DoP encoded DSD can work at...

    Hearing loss and DACs

    You have not provided enough information about your hearing and the non-dac parts of your system to give you an accurate answer to your question. Regarding your hearing, if you are married it is likely that even in the old days of telephone sound quality earlier in your life, you might have...

    Listening Tests and how length of time spent listening alters perception ex.

    Its that we somehow muddle though life getting some things right and other things wrong. We sometimes judge audio gear wrong, cars wrong, people wrong, etc. Other times we do better. In other words its not that we 100% of time fool ourselves with audio, yet are perfectly rational in all other...

    Listening Tests and how length of time spent listening alters perception ex.

    Of course they do, and they do so in all aspects of life. There is overwhelming evidence of human dis-rationality and misperception. Yet, we may choose a CD, a car, a mate or anything else using a brain that couldn't function at all without biases and mental heuristics. That's how biological...

    Listening Tests and how length of time spent listening alters perception ex.

    Amusing story, but what does it really show? It shows that experiments can be devised to demonstrate that people can be fooled. So, can experiments be devised to show what people can hear when the intent is not to fool them? Of course the answer is, yes. Some food for thought: JBL uses a panel...
