Architecture

Use Onion architecture
- Dependencies go inwards. That is, the Core domain doesn't know about outside layers
Use pipeline model to implement workflows/use-cases/stories
- Business logic makes decisions
- IO does storage with minimal logic
- Keep Business logic and IO separate
Keep IO at edges

Minimal example: transcode from MP3 to WMA:
ffmpeg -i input.mp3 output.wma

You can get the list of supported formats with:
ffmpeg -formats

Convert WAV to MP3, mix down to mono (use 1 audio channel), set bit rate to 64 kbps and sample rate to 22050 Hz:

	USE [master]
	GO

	IF OBJECT_ID('dbo.calendar') IS NOT NULL
	DROP TABLE [dbo].[calendar];

	IF OBJECT_ID('dbo.fn_generate_calendar') IS NOT NULL
	DROP FUNCTION [dbo].[fn_generate_calendar];
	GO
