This App allows to create Hi-Fi home audio system with unlimited possibilities

Audio Player ESP is the App that allows you to create an efficient and affordable smart home Hi-Fi audio system with unlimited possibilities. Warning! This is NOT an audio player for your smartphone! This is a DIY hardware project based on аn ESP32 microcontroller.

Features:

-- Requirements:

• Access to a WiFi network (SSID and password)
• A Windows computer is needed at least once to upload firmware
• You need to buy a few cheap hardware electronic components by online shopping (Amazon, AliExpress, etc.) and have some basic skills to connect hardware

-- No Internet account needed. Moreover, most functions can work without Internet access

-- This is NOT a cloud-based project

-- Completely NO ads

-- High quality Hi-Fi sound in your home from 4 sources:

1 - audio files from micro-SD cards up to 1024 GB capacity

2 – optical or coaxial SPDIF input

3 – Internet Radio

4 – Bluetooth Audio

-- Support CD-Audio quality sound as a primarily audio format (stereo 16-bit 44100 Hz)

-- 100% digital audio system, NO analog signal paths, NO background noise, LOW distortion, WIDE dynamic range

-- One-chip class D amplifier with digital I2S interface (SSM3582)

-- Output power up to 50 W

-- 0.004% THD+N at 5 W into 8 Ohm speakers

-- Up to 109 dB SNR and low noise level

-- Automatically scanning and creating playlists

-- Support for digital volume, automatic gain control, and parametric equalizer from your smartphone

-- 32-bit audio data internal resolution

-- Stereo signal level LED indication

-- Stereo 10-band LED spectrum visualization

-- Sound generator functionality for testing audio equipment. Support 32-bit sine generation, multi tones, multi levels, white noise, linear or logarithmic frequency sweep

-- Standard power supply 5V-2A or 5V-3A

-- Extremely low power consumption

-- No need to turn power off. The power consumption is almost zero when no sound

-- Extremely small physical size

-- Can replace most of AV-receivers and some Hi-Fi components, such as CD-players, DACs, Equalizers, Preamplifiers

-- Full remote control from your smartphone

-- User-defined interface on your smartphone

-- Ability to control relay modules triggering by variety types of events

-- Support for up to 8 hardware buttons

-- Support for Amazon Alexa voice control

-- Support for UDP communications

-- Support schedule time for any available actions

-- Support for complicated sequences of any available actions

-- Unlimited possibilities for custom settings

-- Support for web-based access

-- Only one ESP32 Board and headphones are needed to get the first simple result

-- OTA firmware update

-- User-defined hardware configurations

-- Support for obsolete Android devices. The minimum supported Android OS is 4.0

-- Support for multiple ESP32 devices from the same App simultaneously

-- Touch-free gesture control of volume and input selection by using another friendly IR Remote ESP project

-- Easy communication between other friendly devices from IR Remote ESP and Switch Sensor ESP DIY-projects

-- Step-by-step documentation

Attention entrepreneurs!

If you found this project interesting and want to organize mass production of such type of devices, I am open to reach a business agreement. The specific application version for Android and firmware version for ESP32 can be adapted under your ESP32 schematic based on this project.

Please place the word "production" into the subject line of your email to get my attention faster.
