C43198x2 DAC chip neutral and versatile audio quality:

The expressiveness and realism released in the music are reproduced again. It supports 384kHz/32Bit PCM and DSD 256 high-definition audio, and various sound sources are easily decoded. The attached peripheral filter circuit can suppress interference and power supply noise, and more perfect and stable experience of pure audio signals

Tone clarity and low-noise production design:

With a signal-to-noise ratio of 130dB, the device achieves a very low noise level. The distortion rate is only 0.0005% (THD+N). The design ensures that the sound is presented in scenes like mountains and rivers without any noise (1μVrms).

Body construction and aesthetic matching:

TP35 is made of CNC aluminum alloy, precision-processed, compact and portable, and has a distinctive appearance. The surface is sandblasted and oxidized, which can make it laser-engraved, and can present the effect of texture and texture. The transparent acrylic is matched (let you see the real chip inside) and weighs 15G, which makes you portable and easy. Functional form

High-quality functional connection:

High-purity oxygen-free copper shielded wire can reduce interference and provide sound transparency and resolution. Replaceable cables can easily connect various devices, including standard Type-C to USB and optional lightning interface for Apple devices.

Instructions

1. Use the included data cable to connect the mobile phone or other front-end device that supports OTG decoding. After the connection is successful, the TP35 indicator light will be on (red), indicating that the connection is normal. It is recommended that when you use TP35 to connect to the mobile phone for the first time, first turn down the volume of the mobile phone, and then adjust it to a volume that suits you to avoid excessive sound (causing explosion and damage to the ears) and it is recommended to use high bit rate or lossless sound source for a better listening experience.

2. Function key description

-TP35 DAC button volume adjustment function and mobile phone volume adjustment function are controlled independently

-DAC built-in volume has power-off memory function

3. High and low gain function mode switching in UAC mode

·TP35 works in UAC2.0 mode by default after power on. UAC mode cannot be switched during operation.

·When TP35 is disconnected (powered off), press and hold the "volume +" key first, then connect TP35 to the interface of the computer, mobile phone or game console (power on), wait until the indicator light flashes slowly and then release the button, TP35 will work in UAC1.0 mode.

When TP35 is in use, press the +- keys at the same time to switch high and low level modes (gain mode)

*LED display, volume level and output level mode (high and low gain) have power-off memory function (that is, it will save the previous high and low gain effects and the light conditions when the LED is not displayed)

A wonderful primer for those discovering the amazing world of generative AI
Format: Paperback, Format: Paperback
Somewhere in the past year, ChatGPT has gone from "cool, interesting, amusing" to a massively valuable work assistant capable of writing Python scripts, analysing data, and doing lots, lots, more. The key to this? The rapid evolution of OpenAI's GPT models and making my first forays into prompt engineering. If I thought I was getting good, though, this book took me reminded me that I'm just scratching the surface. Halfway through the first chapter I was already furiously scribbling notes in the margins for what I could do better with my prompt writing and by the end of the text I felt like I had gotten a very good grounding - not just in GPTs specifically but in the bigger picture of how these hugely powerful tools were trained and came to maturity. I imagine that few will argue with my assertion that there is lots of hyperbole and "noise" in the AI space right now which, as ever, makes it hard to pick out the signal from the noise. Which is precisely why I sought out an O'Reilly title and I'm very glad that I did. Thorough, excellent, and I hope that this edition will be the first of many. As this rapidly maturing field scales and matures I think that prompt engineering will be an essential discipline to master. Pick up this text to get a good foothold on things.

Understanding AI prompts as a science
Format: Audiobook
Prompt engineering is the art and science of finding the right words to generate the right responses from artificial intelligence (AI). It's becoming a skill in-demand in today's workplaces. It's also becoming an essential skill for life. To understand prompt engineering, you must understand how AI tools understand their inputs. This book explains that to you in many forms. It covers prompting as it intersects all the major AI disciplines, like general prompts (as in a ChatBot), fine-tuning, and retrieval-augmented generation (RAG). It also introduces how prompting intersects a couple of image-generation tools. As a scientist, I appreciate the theoretical approach to these practical matters. Too many people are hacks at AI these days, and any technical understanding can rapidly advance an individual's effectiveness. Prompt engineering is often made fun of as a "soft" topic, but as this book demonstrates, it intersects all the major AI areas. Presumably less garbage in means less garbage out. This book shows how you can make that take place. As typical for O'Reilly materials, this book appeals to people who desire an intermediate-to-advanced understanding of how AI works. It's not for the casual user. Anyone technical involved in professional knowledge generation using AI can benefit from understanding the dynamics "under the hood." It's a good, though perhaps not ground-breaking, textbook for those of us unable to take a class in the subject. Prompt engineering may be a soft topic to many, but books like this ground the field in the science that can make or break a digital or software product.

Comprehensive Guide with Practical Insights
Format: Paperback
This is a solid book for understanding the art and science of working with LLMs and other generative AI models. I always struggled with getting the output I was looking for, and wasn't sure how best to "ask" the models for what I wanted. This book did a great job of laying out the strategies and practical guidance to craft the prompts. There were a lot of tips and tricks, but the overall understanding and framework around prompt engineering has been super useful.

A must read!
Format: Paperback
Hands down, the best book on prompt engineering and implementing LLMs. Really enjoyed Michael and James deep dive. Whether you're technical or not, this book is foundational to a deeper understanding in how to properly explore and implement LLMs.
