Una descripción de las ediciones de “Glitching” del sonido y de la música de Windows

Parte I: Porqué hace mi sonido a veces “interferencia de Windows?”

Windows es un OS rico y complejo diseñado para los usuarios de los trabajos múltiple que tareas deben compartir el acceso al hardware y a los recursos escasos del sistema. Desafortunadamente, a pesar de décadas múltiples de avances increíbles en arquitecturas de la PC y de la CPU, hay interacciones no triviales, complejas entre los usos, procesos, y dispositivos en uniforme los ordenadores personales más avanzados que hacen una tarea supuesto “fácil” - como jugar detrás música sin interferencias ocasionales - mucho más difícil que puede parecerse a primera vista.

Otra manera del pensamiento de esto: se parece impar que una PC moderna >$2000 puede a veces tener apuro seamlessly el jugar de música trasera cuando $20 lectores de cd pueden effortlessly música del aparato de lectura sin interferencias.

¿Tan porqué la interferencia de muchas $2000 PC de vez en cuando mientras que juega música trasera? La respuesta rápida es ésta: Windows no es un dispositivo de la solo-función como un lector de cd.

Una respuesta levemente más larga va como esto: incluso una máquina media de Windows es hoy de uso general simultáneamente pues un jugador de medios, un procesador de textos, un proyector de la presentación, una desmenuzadora de número de la hoja de balance, un authoring tool, un redactor de la foto, un video de los medios servidor, una herramienta de la composición de la música, un dispositivo de las comunicaciones, un Search Engine, un detector del virus, un compresor y un descompresor de los datos, y un encargado de reserva. Y éstos son solamente algunos de las tareas y de los procesos posibles que se funcionan al mismo tiempo en los centenares de millones de máquinas de Windows que sean funcionando hoy. Cada uno de estas tareas o procesos, en el aislamiento, gravaría apenas los recursos del hardware de PC moderno. Pero en nuestro mundo de los trabajos múltiple, los conflictos inevitables del recurso ocurren a veces entre el ecosistema enorme y diverso del hardware de Windows que permite estas tareas. Incluso en la máquina más costosa, más a estrenar, las interferencias ocasionales pueden ocurrir si y cuando el sistema procura dividir sus recursos finitos entre estas actividades múltiples, diversas, independientes, energía-hambrientas.

Qué es ¿una interferencia?

Una interferencia es un error, un boquete o un estallido perceptible en el sonido causado por las discontinuidades en la audioseñal durante aparato de lectura o la grabación que resultan de problemas de proceso o que miden el tiempo. Las interferencias durante aparato de lectura de la música pueden sonar como un “estallido ruidoso” o como una breve rebanada del silencio insertó aleatoriamente donde su música debe haber estado. Algunos clientes también han descrito lo que “glitching” en sus propias palabras como:

• el audio para un poco
• se rompe para arriba
• entrecortado
• el chascar
• corrupción
• crujido/chisporroteo/crackly
• interrupción
• inquietudes
• jumpy
• el saltar/salto/saltos

For the purpose of this discussion, let’s lump all of these descriptions together under one general class of problems and call these “glitching.” While a glitch that happens during music playback can be annoying and unsettling, a glitch that occurs while you are recording or communicating with someone can result in frustrating and unacceptable data loss.

What causes my Windows sound and music to glitch?

Digital media processing is time-sensitive. Playback requires specific work to be performed by a given deadline — otherwise presentation or data loss can occur. A “glitch” occurs when a deadline for time-sensitive processing is missed or when time-sensitive data is lost.

For example, in Windows Vista, playing back music involves “work” that must be done at least every 10 milliseconds so that there can be a continuous stream of music out to your speakers. The “simple” task of playing back music consists of the following steps, all of which must be completed before a strict deadline:

1. a small chunk of data from a music file needs to be read from a disc (CD or hard drive)
2. this data needs to be “decompressed” or “decoded” (usually in system memory) so it can be streamed out to your speakers in a format that your sound hardware understands
3. the decompressed sound data needs to be copied from system memory to your sound hardware memory
4. the data in your sound hardware needs to be sent to your speakers at the appropriate time
5. repeat steps 1-4 flawlessly every 10 milliseconds (ms)

Windows Vista : Latest Update KB940510 to Stop pirates

When the update will be installed, no functionality of the system will be affected. If it detects and exploits you will be provided a link that would describes how you can remove the exploits. Once the exploits are removed you will be asked to activate your Windows copy with a valid product key. If you don’t want to remove the exploit then Windows may disable the exploits and then ask you activate Windows using a valid product key (surely there would be a nag screen). This update has no uninstaller.

List of Vista SP1 problems

Vista SP1 is officially only available for enterprise customers, but the reports about problems caused by this service pack are piling up. This post contains a list of all SP1 issues I am aware of.

I have discussed some of them before, but I thought it might be a good idea to create a list of all known Vista SP1 issues to keep track of them. I will update this post whenever I encounter new ones.

Device driver problems

This issue was the reason why Microsoft postponed the general release of SP1 to mid-march. It seems not to be a big problem for tech savvy Vista users. This article (KB 948187) has more.

Programs that have problems with Vista SP1

I mentioned before that Vista SP1 doesn’t solve compatibility problems, but it causes new ones. This article (KB935796) lists all known programs that don’t work properly with Vista SP1. I suggest you check them out before you install this service pack. Please, let us know if you experienced troubles with other apps that are not in this list.

The endless reboot issue

This problem of Vista SP1 is causing a lot of stir. A pre-requisite update (KB937287) triggers endless reboots on some machines. Microsoft suspended the automatic distribution of this update. I installed this update before, but I didn’t experience this problem. I just checked Windows Update and it was available again. Before that, I was able to install Vista SP1 without this patch anyway. So it seems like this issue is not as bad as it seemed at first. KB949358 has details on how to solve this problem if you are affected.

The sleep mode problem

Milo reports that some systems with SP1 crash when attempting to wake up their PC from sleep mode. I have experienced the same problem on some Vista machine without SP1. A BIOS update might be of help in such cases. However, I don’t know if the problem described by Milo is a new one. He thinks that it might be related to the reboot issue. However, I think it must be something different because the reboot problem isn’t about sleep mode.

The Windows Mobile Device Center issue

There are reports that Vista x64 SP1 has been released accidentally to Windows Update. ITWire received emails from users who experienced problems after installing SP1. One is that the memory and performance rating is not displayed anymore, and the other one is about the Windows Mobile Device Center. Based on the screenshot they published, the latter one looks familiar to me. I got the same meaningless error message sometimes when I connected my Windows Mobile 6 device to different desktops running the Windows Mobile Device Center. The only solution I found was to reset Windows Mobile. I don’t know if this is really the same problem, but it could be that SP1 causes an authentication problem which probably was the reason for the error message in my case.

GPMC (Group Policy Management Console) will be uninstalled

If you manage Group Polices for Vista machines in your PC, then I wouldn’t install SP1 because GPMC will be removed after the installation. Microsoft plans to release a new version, but as far as I know, this is not yet the case.

The sound problem

The German Windows Vista blog and Aaron discovered a problem with the sound system. It seems that this is related to the driver problem discussed above. However, Microsoft dedicated a particular article (KB948481) to it.

Even though some media are making a big deal out of this SP1 issues, I don’t think that they are really serious so far. Of course, those who are affected might have a different view about it. But do you remember about the troubles that service pack 2 for Windows XP caused? Well, XP is everybody’s darling now.
