lyra | A Very Low-Bitrate Codec for Speech Compression
kandi X-RAY | lyra Summary
kandi X-RAY | lyra Summary
The basic architecture of the Lyra codec is quite simple. Features are extracted from speech every 40ms and are then compressed for transmission at a bitrate of 3kbps. The features themselves are log mel spectrograms, a list of numbers representing the speech energy in different frequency bands, which have traditionally been used for their perceptual relevance because they are modeled after human auditory response. On the other end, a generative model uses those features to recreate the speech signal. Lyra harnesses the power of new natural-sounding generative models to maintain the low bitrate of parametric codecs while achieving high quality, on par with state-of-the-art waveform codecs used in most streaming and communication platforms today. Computational complexity is reduced by using a cheaper recurrent generative model, a WaveRNN variation, that works at a lower rate, but generates in parallel multiple signals in different frequency ranges that it later combines into a single output signal at the desired sample rate. This trick, plus 64-bit ARM optimizations, enables Lyra to not only run on cloud servers, but also on-device on mid-range phones, such as Pixel phones, in real time (with a processing latency of 100ms). This generative model is then trained on thousands of hours of speech data with speakers in over 70 languages and optimized to accurately recreate the input audio.

I am looking for a very basic pipeline template that allows me to correctly index all available fields of a log-message.
I use Spring Boot (2.1.x) out of the box, deploy it to Cloud Foundry and log via stdout/logdrain to Logstash and eventually to Elasticsearch.
I already searched the internet and found only one template for Cloud Foundry apps:

QUESTION
Note: This question is specific to the Elasticsearch service provided by Swisscom
Question: (a.k.a: tl;dr
)
What configuration is required to get the official Kibana docker container to connect to a Swisscom Elasticsearch Service?
Background:
Up until about a year ago the Swisscom public cloud offered a full ELK stack (Elasticsearch, Logstash, Kibana) in a single service offering. When this service was discontinued, Swisscom replaced it by just offering the Elasticsearch service and asked clients to setup their own Kibana and Logstash solutions via provided CloudFoundry build_packs
(Kibana, Logstash). The migration recommendation was discussed here: https://ict.swisscom.ch/2018/04/building-the-elk-stack-on-our-new-elasticsearch/
More recently, the underlying OS (called "stack") that runs the applications on Swisscom's CloudFoundry-based PaaS offering, has been upgraded. The aforementioned build_packs
are now outdated and have been declared as deprecated by Swisscom. The suggestion now is to move to a generic Docker container provided by Elastic as discussed here: https://github.com/swisscom/kibana-buildpack/issues/3
What I tried:
CloudFoundry generally works well with Docker containers and the whole thing should be as straight forward as providing some valid configuration to the docker container. My current manifest.yml
for Kibana looks something like this, but the Kibana application ultimately fails to connect:

A current project requires us to use Vega Visualization Grammar wherever possible and otherwise fall back to D3.js. 3D-surface plots are not part of the Vega's gallery of examples, however Vega Documentation makes me optimistic that we could create our own graph representations. Could somebody advise me how to do generate 3D surface plots with Vega? Any tutorial you suggest? Or maybe even a brief recipe assuming that I have a data set of say a few 100 (x,y,z)
tuples?
Edit: The goal is quasi-static graphics with linear-interpolation between the points, in R we would probably do it like with a wireframe.
Obviously, I extensively used search engines, but see many results on astronomic research on α Lyrae.
...ANSWER
Answered 2018-Sep-19 at 16:343D surface plots are not supported by Vega. You might try another library, like threejs.

When I compile and flash an ESP32-LYRATD-MSC with the official audio recording examples, I get an es_write_reg
error after configuring the ES8388 codec driver.
What could have changed from the LYRA or WROVER kits to the LYRATD-MSC that could cause the error?
...ANSWER
Answered 2019-Mar-10 at 19:39This is a known issue with the samples. The ESP32-LYRATD-MSC ships with the ZL38063 DSP chip, but as you can see from sample, it expects to configure the ESP8388:

I am trying to do a layout of cells similar to the output in this picture:
But I need to do a lot of rows and I want the columns to be a specific size and NOT WRAP to another line if it goes over the size of the screen. For instance, say I have 10 columns, with each column being 200 pixels. I want a horizontal scroll if there are too many columns to fit on screen, rather than wrapping the other columns. My code is something like (I got it off the W3Schools.com website when my first attempt using a table did not work):
