Extracting DVD-Audio on Linux, the modern(ish) way


A cute penguin.

DVD-Audio (henceforce DVDA) is an unloved and mostly forgotten audio format. Nevertheless, there's a large back-catalogue of music which is still trapped on ancient discs encoded in the proprietary MLP format. A few years ago I wrote about how to extract the audio using the obsolete Windows program DVD-Audio Explorer. I wanted to be able to run the extraction via the command line, which means trying to find a native Linux app. I tried Python AudioTools but I got lost in an endless maze of…

HDCP is ridiculously annoying - DRM sucks for consumers


TV showing error message.

I decided to treat myself to an upgraded home cinema experience. But mandatory copy-protection has meant I've spend the weekend trying and failing to get things working, rather than watching glorious 4K HDR 10 bit movies. Here's the problem: Why am I getting the error "This content can not be displayed because your TV does not support HDCP 2.2."? I have four pieces of kit in the mix, all of which claim to support HDCP's Digital Restrictions Management: Amazon Fire TV Stick - the new 4K…

Convert Surround Sound WAV albums to individual opus files


Screenshot of a multitrack audio export.

As ever, notes to myself. This is a method to take a .wav and .cue and transform it into individual files. In this case, .opus. Transform to .flac FLAC is a good intermediary file format, especially for surround sound files. avconv -i file.wav out.flac Transform to .opus An optional step if you want smaller files. Maximum quality for 6 channel audio. opusenc --bitrate 4096 out.flac out.opus Create an .mkv Add to an MKV with all the chapter information. mkvmerge -o test.mkv --chapters…

Deconstructing The Sounds Behind The Lightsaber Dream Sequence


Just a bit of fun for a Friday afternoon - and spoilers ahoy! Star Wars VII contains the most magnificence dream sequence. When Rey lays her hand on a lightsaber for the first time, the world dissolves as a cacophony of audio hallucinations plague her. It's a short sequence - lasting just under a minute - but the sound design is beautiful. After seeing the fabulous Path of a Lightsaber video I thought I'd have a go at deconstructing all the voices which went into creating such a mesmerising…

Exporting Multitrack Surround Files in Audacity


Screenshot of a multitrack audio export.

Notes to myself! Suppose you want to create a surround sound file using Audacity. The app is a little obtuse, so this may clear up some confusion. When exporting, Audacity defaults to mixing down to stereo. You must adjust these settings: Edit → Preferences → Import/Export → Use Custom Mix Lay out your audio. Keep each track as mono. You can have as many tracks as you like and then downmix them later. File → Export If you choose a surround compatible format, like .ogg, you will be abl…

Splitting a Surround Sound Audio File in Ubuntu


Screenshot of multitrack audio in Audacity.

See this update for a better way to do this. Being mostly notes to myself and following on from my post on Quadrophonic files. I have: A DTS album stored as a .WAV A .cue file with chapter markings I want: The single large file to be split into individual chapters with one file per chapter. Each file to be multitrack (that is, to stay in surround sound) It turns out, that there is no simple way to do this. There are tools to split stereo wav files by their cue sheet,…

Dealing With Quadrophonic / DVD-A Files In Linux


These are mostly notes to myself. These all comply with the UK's new copyright laws. Check your local laws, kiddies! DVD-Audio (called DVD-A or DVDA) never really took off. It's hard to find the discs and compatible hardware. Nevertheless, I want to listen to these high-resolution audio tracks under Linux. In these examples, I'm using Ubuntu - but any modern system should cope. Ripping DVD-A In theory, DVD Audio Tools should work. In practice, I found no guide to compiling the software …
