Bluetooth audio in Linux: ALSA and LDAC

Audio using pure ALSA (no PulseAudio) and LDAC codec

Preview

Ever since Bluez dropped support for Bluetooth audio using ALSA, people have been using PulseAudio to connect audio devices in Linux. However, there's a project called BlueALSA which supports high-quality cutting-edge codecs such as LDAC, and it works with pure ALSA. Read the article to see how to use it.

Detachable cable and wireless mod for the AKG K701 headphones

Tested with the new FiiO BTR3 (a review)

Preview

For a long, long time I've been thinking of modifying my original Austrian-made AKG K701 headphones to have a detachable cable. After owning the headphones for eleven years, I finally did it. At the same time I kind of made them wireless using the new FiiO BTR3. Check out the article to see how they fit together.

WebLED: my first IoT project on the Arduino platform

...or: how to open a garage door using WiFi

Preview

For a long time I've wanted to get more into embedded stuff and closer to the physical world when it comes to computers. As a kid I was quite interested in electronics and tweaked some small stuff, but I never really got into programming anything. Now with the market full of cheap Arduino-compatible chips, I decided to hook myself up into the Internet of Things and make a WiFi-operated garage door opener. Check out the article for an overview of the project.

How to join a Skype for Business meeting from Linux

Summary: use a Windows virtual machine

In a previous article I discussed KVM and its audio capabilities. As of now there still isn't a nicely working emulated audio device for Windows 10 guests let alone a working Skype for Business client for Linux. In my day job I have to attend Skype for Business (formerly Lync) meetings quite often but it was impossible using my work laptop, which has Linux. I finally took the time to check out how USB passthrough works in KVM and solved the problem. Read the article to see how.

Easy acoustic tweaks for your room

Stopping flutter echo, equalizing with ALSA and gstreamer

Preview

Most mortals have to listen to music in a somewhat small room - a closed space, which will usually result in boomy bass at some frequencies, and terrible flutter echo in the upper end of the audible spectrum.

Read this article to find out quick and cheap tricks to remedy the problems.

Configuring ALSA for pro hardware setups

Advanced .asoundrc / asound.conf examples

Nowadays most Linux distributions probably use PulseAudio for audio. In my opinion, not that long ago it was completely unusable. I still do not use it on my main rig, and find it mostly an unnecessary piece of software that potentially creates latency or configuration problems. In most cases, you usually don't really need it. In this article I'll show some tricks on how to write a killer ALSA setup. Recommended for audiophiles, movie lovers, recording artists and other crazy folks.
