mp3rgain ~ Lossless MP3/AAC Volume Adjustment
A modern mp3gain / aacgain replacement written in Rust. A native GUI application (mp3rgui) is available for users who prefer a graphical interface.
mp3rgain adjusts MP3 and AAC volume without re-encoding by modifying the global_gain field in each frame. This preserves audio quality while achieving permanent volume changes.

RTL Utility ~ Measure Round Trip Latency
RTL Utility is a tool for measuring the Round Trip Latency of your Digital Audio Workstation (DAW) and audio interface. The utility is used for low latency performance testing by system builders, reviewers, device manufacturers and at dawbench.com.
When your DAW sends data to your audio interface for playback, it doesn’t send a continuous stream of data one bit at a time. What it does is fill up a section of RAM called a buffer and sends that in a single message when it is ready. Before sending the next message it has to fill the buffer again. This wait time introduces a latency, or delay, between something happening in your DAW and when you actually hear it.
While you are recording, the audio interface buffers and sends data to your DAW in a similar fashion. This introduces latency into your recordings.
If you send a signal from your DAW, out through the audio interface and back in via a loopback patch, then there will be a round trip latency which is the sum of the output and input delays. This is the RTL.

fdkaac ~ Command Line Frontend For libfdk-aac Encoder
dkaac reads linear PCM audio in either WAV, raw PCM, or CAF format, and encodes it into either M4A / AAC file. If the input file is "-", data is read from stdin. Likewise, if the output file is "-", data is written to stdout if one of streamable AAC transport formats are selected by **-f**. When CAF input and M4A output is used, tags in CAF file are copied into the resulting M4A. github.com/nu774/fdkaac github.com/mstorsjo/fdk-aac launchpad.net/ubuntu/bionic/+package/fdkaac packages.debian.org/stretch/fdkaac

Shairport Sync ~ Unix AirPlay Player
Shairport Sync is an AirPlay audio player – it plays audio streamed from iTunes, iOS, Apple TV and macOS devices and AirPlay sources such as Quicktime Player and ForkedDaapd, among others.
Audio played by a Shairport Sync-powered device stays synchronised with the source and hence with similar devices playing the same source. In this way, synchronised multi-room audio is possible for players that support it, such as iTunes and the macOS Music app.
Shairport Sync runs on Linux, FreeBSD and OpenBSD. It does not support AirPlay video or photo streaming.
