Samsung Galaxy S4, Wolfson WM5102 & "qualcomm audio"

[Jaxxon]

Segun XDA parece que el S4 montara un wm5102

Description

The WM5102 is a highly-integrated low-power audio system for smartphones, tablets and other portable audio devices. It combines wideband telephony voice processing with a flexible, high-performance audio hub CODEC.

The WM5102 digital core provides a powerful combination of fixed-function signal processing blocks with a programmable DSP. These are supported by a fully-flexible, all-digital audio mixing and routing engine with sample rate converters, for wide use-case flexibility. The programmable DSP is optimised for Wolfson's wideband voice processing which includes multi-mic noise reduction and echo cancellation. Many other audio algorithms can be implemented. Fixed-function signal processing blocks include filters, EQ, dynamics processors and sample rate converters.

A SLIMbus interface supports multi-channel audio paths and host control register access. Multiple sample rates are supported concurrently via the SLIMbus interface. Three further digital audio interfaces are provided, each supporting a wide range of standard audio sample rates and serial interface formats. Automatic sample rate detection enables seamless wideband/narrowband voice call handover.

Two stereo headphone drivers each provide stereo ground-referenced or mono BTL outputs, with noise levels as low as 2.3μVRMS for hi-fi quality line or headphone output. The CODEC also features stereo 2W Class-D speaker outputs, a dedicated BTL earpiece output and PDM for external speaker amplifiers. A signal generator for controlling haptics devices is included; vibe actuators can connect directly to the Class-D speaker output, or via an external driver on the PDM output interface. All inputs, outputs and system interfaces can function concurrently.

The WM5102 supports up to six microphone inputs, each either analogue or PDM digital. Microphone activity detection with interrupt is available. A smart accessory interface supports most standard 3.5mm accessories. Impedance sensing and measurement is provided for external accessory and push-button detection.

The WM5102 power, clocking and output driver architectures are all designed to maximise battery life in voice, music and standby modes. Low-power 'Sleep' is supported, with configurable wake-up events. The WM5102 is powered from a 1.8V external supply. A separate supply is required for the Class D speaker drivers (typically direct connection to 4.2V battery).

Two integrated FLLs provide support for a wide range of system clock frequencies. The WM5102 is configured using the I2C, SPI or SLIMbus interfaces. The fully-differential internal analogue architecture, minimal analogue signal paths and on-chip RF noise filters ensure a very high degree of noise immunity.

Wolfson CEO Mike Hickey said, "Our continued success with Samsung, particularly within its range of smartphones and tablets, is testament to the unrivalled quality of our HD Audio Hubs, and the unique features in our products that allow manufacturers to create differentiated audio experiences."

While Samsung chose the WM1811, Wolfson has already moved on and announced its WM5110 chip, which features a 110dB signal to noise ratio and supports six or eight channels. The firm said it is already sampling the WM5110, so perhaps Samsung's Galaxy S4 will include it. µ

Wolfson announces quad-core WM5110 audio chip for smartphones


CHIP DESIGNER Wolfson has announced its WM5110 quad-core audio chip for high-end smartphones.

wolfson-wm5110Wolfson, which supplies audio chips in a vast array of smartphones and tablets along with HiFi equipment, has announced its first quad-core audio system-on-chip (SoC) dubbed the WM5110. The firm claims that the chip has a 110dB signal-to-noise ratio and the four cores clocked at 150MHz offer 600 MIPS of processing power using just 3mW power.

According to Wolfson the WM5110 has ambient noise cancellation and acoustic echo cancellation technologies that can reduce 32db and 20dB of noise and echo, respectively. The firm also released an accompanying software development kit that smartphone and tablet makers can use to apply their own 'audio signature' which Wolfson told The INQUIRER is part of what device builders are using to try to differentiate themselves.

Duncan Macadie, product line manager for Audio Hubs at Wolfson Microelectronics told The INQUIRER, "The WM5110 offers a significant step up in analogue performance, audio performance and audio processing capability while offering a step down in power consumption, so all the key things our tier-one customers are pushing. It closes the gap between the products we sell into the high-end HiFi and the products we sell into the low power handheld products. There has been in the past a gulf in performance between those two products, but they are really coming together as we see handset manufactures and tablet manufacturers deliver a true HiFi audio experience with their products."

Wolfson said SoC chip vendors are moving audio off the main application processor as process nodes shrink. The firm said it believes that as chip vendors such as Qualcomm, Texas Instruments and Nvidia use smaller process nodes they will find that keeping high-quality audio on the same die will become increasingly harder, leading to growth in demand for increasingly complex audio chips.

Wolfson said its WM5110 audio chip is available for limited sampling now in the W-CSP package. µ

Nueva info del chip de sonido

[dacari]

Es verdad, si vemos las características y ficha técnica de cualquier chip, sobre el papel, es todo perfecto, la realidad ya la veremos.

Supongo que hace tiempo que el mayor dolor de cabeza de Wolfson debe ser el consumo o encontrar el mayor equilibrio entre calidad de sonido y consumo.

[Jaxxon]

Nuevos rumores,  las dos versiones seran la 9500, chip exynos con chip wolfson (aun se discute que si con chip lte o no)  y el 9505, con el chip snapdragon 600 y chip de audio qualcomm como en el one,  y se rumorea que sin radio fm (el 9500 si)
Cuando haya algo oficial lo cuelgo

Vamos el mismo estigma de todos los android, yo samsung ni agua, desde luego, por ahora no, no he tenido el S4 en la mano, pero el S3 no me convenció y el Note 2 ya he comentado los problemas de construcción, así que me lo pensaré muy mucho antes de comprar algo Samsung

Gonzalo no te doy la mano más, temo por mis huesitos. El Note 2 cruje un poco si lo aprietas como queriendo sacarle jugo... que quizás se pueda y deba darlo.

Yo estoy muy contento con el cacharrín (es pequeñito, sí)  y eso que vengo del que para mi es el mejor móvil en cuanto a terminación y "feel" el Iphone 4 (4s)

[GonzaloM]

Mira donde el volumen encima en el bisel y verás que no ajusta bien, al menos el mío no lo hacía, ahora bien, que no soy ningún godzilla ni nada parecido :jejeje: La mano se estrecha firmemente pero sin intentar romper los huesos de nadie :lolll: :lolll: :lolll:

[rafaunivega]

En mi Note 2 no se ve ni nota nada raro
Tambien dicen que se estropea el marco de mirarlo y en el mio tampoco ha pasado
Supongo que con esa cantidad de produccion alguna partida saldra con tara

Esperemos que sea un repro-movil que esté a la misma altura de repro como lo parece como móvil pero tengo mas esperanzas en el HTC ONE que por cierto es, para mi gusto, mas bonito y que por otra parte será algo mas "barato". Pero aún así esperaré algún tiempo a que los dos móviles permanezcan el mercado para así conocer de que pie cojean ambos.

Por cierto, muevo el post al foro  Smartphones Android si no te importa jaxxon ya que lo has posteado en el foro de repros de samsung.

Saludos!!

Nada como veáis, es que como estábamos hablando concretamente del sonido pues para aquí que se fue

[jowi]

Jaxxon thanks por la info ..... sí que son buenas noticias que mantengan el chip wolfson porque no sería la primera vez que Samsung dá un paso atrás en este sentido.....y es de suponer que sí no mejora, al menos igualará el sonido del S3.

Muy chulas todas esas cosas pero como se comportará como reproductor? Esa es mi duda... Gracias por la info.
