Wav to PICmicro ASM, C Converter Program

A program that converts wav format files to PIC Assembler ASM and PIC MicroC C code to upload audio files to PIC or other microcontrollers has all the details (in English) How to use PIC outputs with a simple additional circuit, the resistors appear as 2R in the circuit, they are generally perceived as 2Ω. Note 2R only resistor names and values are written in the saved code file.

BTc Sound Encoder 3.0 Software A standalone software utility for digital audio encoding. BTC Sound Encoder is software I wrote to convert audio (in wave files) into a 1-bit format that can be played on very cheap hardware like microprocessor chip (PIC, Atmel, Motorola etc.). The coding process is based on my BTC Binary Time Constant algorithm

You open any .WAV file that contains audio, this software converts the audio to 1-bit format and you load the 1-bit audio into your cheap hardware like a PIC microcontroller and you can play the audio with almost no other hardware needed. It does not need a DAC (Digital to Analog Converter IC).

This new BTc Sound Encoder v3.0 replaces all previous versions. How it works This encoder software also allows you to try different BTc encoding parameters and listen to an approximate sample of the encoded data played back by the PC sound card. BTc Sound Encoder is a standalone tool for converting audio files into a 1-bit bitstream format that you can play on a PIC or other micro simply by adding a resistor/capacitor network.

BTc Sound Encoder generates 1-bit data by digitally modeling an RC filter, so when the bitstream is played through a real-world RC filter, the analog audio will be the closest possible reproduction of the original wave file. raw hardware. BTc Sound Encoder also displays the characteristics of the resistor and capacitor values used in the encoding model.

Limitations? This Version 3.0 now increases the maximum wave file length to 4 Megasamples (4,194,304 samples). At a playback bitrate of 44.1kHz, it yields 95 seconds of total audio playback time. Sound quality This is not a .MP3 player for music!

This system lets you play simple audio (usually speech) on very cheap basic hardware (like a small PIC or AVR microcontroller that you can buy for a few dollars).

Audio playback at low bitrates can be scratchy and hissing, but still produce speech you can understand; this is talking remotes etc. It is suitable for simple devices such as talking robots and talking household appliances etc. use it.
