![]() In my test system I run a very high-end PC-based music server and the differences between JRMC and JPLAY were subtle, but I felt that I could hear them. If any software makes a difference, it would be JPLAY, but many people have claimed that it does not offer improvement over JRMC. This is an enthusiast level software, is a bit of a process to set up and tedious to use, but represents the most technically intelligent software available. For an audio-only alternative you can check out CPLAY, which is simpler, open source, and sounds a little better too. The interface isn’t as nice and it’s not quite as easy to use, but many folks dig it. A similar (and free) alternative is Foobar2000, which has several plugins and nearly identical sound quality. The good news is if you don’t want to mess with settings you don’t have to, it pretty much plays right out of the box. For barebones enthusiasts this software may pack too many options, too many settings, and too much freedom. They have also integrated a memory playback feature, which was a big selling point on higher-end software available. The addition of ASIO, Direct Sound, Wasapi, and Kernel streaming is a big bonus over entry-level playback software. It can play anything and offers access to a very powerful DSP engine.The feature set and sound quality improvements in this software make it a significant leap up over its windows media center alternative. ![]() It sports a sleek, easy-to-use interface, various GUI adjustments, and a settings menu with more options than a Vegas buffet line. So as far that bits are concerned, it's bit perfect, but withadditional harmonic content that shouldn't be there.įirst up is JRMC (as the cool kids call it). The square wavemay still resemble a one or a zero, but it contains additional frequencycontent. This introduces harmoniccontent into the square wave that shouldn't exist in the music. Jitter is an alteration of the duty cycle, when thatjitter hits the digital interface chips, a DAC for instance, that jitter isseen as an amplitude error and creates an alteration of the frequency response.Amplitude distortion itself is created by noise voltages that either add orsubtract from the amplitude of the square wave. A square wave, however, reacts a little differently than itssine wave counterpart. If the power supply introduces noise or there is jitter on the squarewave this results in a square wave that is not identical to the original.Because the square wave is an analog signal it is still susceptible to noiseand distortion. Looking at the concept of bit-perfect, it's arguablyimpossible to have bit perfect playback in a real-time system because there areno bits. Because audiois real time, there is no error correction that can be done to this squarewave, any resulting wave form IS your music. That new version ofthe square wave is also created from power in the power supply. Basedon the input voltages, logic switches create a new version, a duplicate, of thesquare wave (either theoretically identical or altered). A computer is made up ofbillions of transistors, all switching very quickly to changes in logic(mathematical algorithms created by the operating system and software). The timing, or duty cycle, along with the amplitudedetermine the frequency response of that square wave. This PWM signal has both amplitude characteristicsand timing characteristics. This pulse width modulation is an analogrepresentation of what we conceptualize as a digital signal and is created byvoltage in the power supply. Real time processes in a computer take the form of a square wave,specifically a pulse width modulation. Even if an application loads data into memory forprocessing, everything before and the whole operation after is a real timeoperation. Let's all start by agreeing that audio is areal-time process.

DoP is the special open protocol to coding DSD into PCM audio stream. ![]() Also, WASAPI (with DoP) interface may be used to playback (including bit-perfect). As a result, you will be able to listen to your tracks at the highest quality possible. Is able to work with iTunes and provides a bit perfect rendition of your audio files. 2,316 downloads Updated: OctoCommercialware. BitPerfect opens a world of clearer, more present sound that you never. Tim Murrison’s BitPerfect 2.0.1 (Mac App Store link) shows what iTunes music is capable of and is an audiophile’s dream. Conventional wisdom states that in order for a system to be bit perfect it must act as a pass-through device, not altering the digital data in any fashion through the. Before diving into the software comparison, I need to address bit-perfect playback.
