Linux Audio Planet - Latest News

In the cross-over between the era of tapes into that of MP3s, you’d see quite a few of those special cassette tapes that were actually digital music players inside. Some simply provided a 3.5 mm input, while others were complete MP3 players or Bluetooth receivers that just happened to also output to the magnetic read head of a cassette player. Recently [Jonathan Rowny] decided to make his own version of the latter. Although getting the actual audio signal into the read head is easy enough – requiring little more than its equivalent being used as a write head on the cassette side – actually interfacing with the player’s mechanisms like auto-stop, reverse and so on requires the use of some gearing that detect motion on what would be the tape spools, as well as transfer the motion from the take-up spool to the other spool so that features like the auto-stop mechanism don’t get triggered. A lot of inspiration here can be found in e.g. the videos made by [Clint] of [Lazy Game Reviews] who looked at a number of examples – including their internals – over the years, with various levels of functionality. For this particular implementation an ESP32-S3 module is used for the brains, along with a microSD card reader for music and a PCM5102 I2S audio codec to create the analog audio signal. The gears were printed using an SLA printer and seem to work all right. Unfortunately he didn’t realize the importance of the capstan as the mechanism that actually transports the tape, so its motion was not measured as is done in the better cassette adapters. This will likely be corrected in a future iteration, however.

As should be obvious from browsing our website for any amount of time, Ubuntu Studio releases a Long-Term Support (LTS) release every two years. The latest LTS release happens to be our latest release: 26.04. What’s more is we just released 26.04.1, a roll-up of bugfixes and security updates, on August 27th. Also announced is the “Butllet-Proof” KDE Initiative, where Kubuntu Focus, Techpaladin Software, and KDE e.V. are working together to make Plasma 6.6, along with KDE Frameworks, an LTS release as well. This means that Techpaladin, Kubuntu, and Kubuntu Focus will be working to fix bugs in the version of the desktop environment and back-end libraries released in Ubuntu Studio 26.04 LTS. This means that, while Kubuntu will be primarily working on the Stable Release Updates as provided by KDE, Ubuntu Studio uses the same packages that get these updates. Our project leader, Erich Eickmeyer, has been doing what he can to help support Kubuntu with this task from his side, while the Ubuntu Studio team (including Erich) focuses on bug fixes to the multimedia applications included with their own Stable Release Updates for the life of 26.04, which is three years total until April 2029. That, combined with Ubuntu Pro (free for every user up to 5 simultaneous machines) means you will not only receive bugfixes better than in the past, which was done at best effort, but also benefit from the security updates provided by Canonical. Yes, even Ubuntu Studio can use Ubuntu Pro. Do note that Ubuntu Pro will not extend the support time period for Ubuntu Studio, but give the added benefit of sponsored security updates. If you would like to help with everything Ubuntu Studio has going on, from supporting the LTS to supporting the upcoming 26.10 release due in October, please feel free to join us! Additionally, while there was an initial jump in monetary support following the 26.04 LTS release, it has dropped-off considerably. Please consider becoming a monthly monetary contributor to help support this project. Remember, our website now has a monthly cost along with the usual cost of packaging and development. If you cannot commit to a monthly monetary contribution, please consider at least a one-time contribution, even if you’ve given before. Even if it’s just a tank of petrol! For those already giving, thank you so much for your continued support. It means the world to us, and allows us to continue giving you and others this operating system for free! You’ve helped countless people throughout the world!

It’s technically true that any piece of software can be reproduced in hardware, although modern software’s size and complexity generally makes this a non-starter. But if we go far enough back in time, older software becomes easier and easier to implement in hardware. The original DOOM from 1993 might one day be recreated in full this way, but that day is not today. Instead, [Nick] has recreated the original music from that game, playing the opening track in nothing but 555 timers. The circuit starts with a 555 timer that acts as a system clock with a rate of just over 7 Hz. These pulses feed a binary counter which in turn feeds a decoder, giving the circuit 15 positions. Each output of the decoder feeds to a diode matrix which stores information about what pitch the circuit should play. The circuit only needs to play six pitches so the diodes effectively connect each moment in time to one of these six notes. From there the circuit feeds into a set of switches which select different resistor networks of another 555 which is actually responsible for producing sound. The resistor networks have different values to adjust the timing of the 555 to produce different pitches. Of course this entire exercise is largely academic as almost any microcontroller would be able to be programmed to play this chiptune quite easily, but it’s not a bad idea to get down into the weeds of digital logic from time to time in order to refine one’s skills and knowledge about what’s really going on in the inner workings of circuits. Or, go even deeper than that and build the logic gates themselves from first principles.

After a somewhat unusual release process, we are pleased to announce Ardour 9.8. Notable features in this release include some initial steps in musical scale support, the return (after perhaps a decade) of robust data recovery after crashes/power outages while recording, and some improvements to clip recording. As usual, there’s a host of bug fixes and quality of life improvements.

A new release of gst123, my commandline media player based on GStreamer is available. The main new “feature” is probably that it now can play videos without crashing on Wayland, although it still relies on Xwayland to do so. See release link for full list of changes.

Work in progress.. feel free to edit this wiki-page if you can improve it. About a3vtl.img is a live-system to evaluate the Ardour3 video-timeline. Live-system - you run it from a USB flash drive. It won't touch your hard-disk and does not require installation. It comes with a whole bunch of audio-software and can be used as studio to go, but you're better off to rely on a dedicated distribution for the latter (e.g. AVLinux, kxStudio, Ubuntu-Studio,…). Prerequisites x86 compatible PC ≥ 1GB RAM USB-flash-drive ≥ 2GB Installation You need to write the disk-image to a raw-device (USB-stick, CF-CARD,..) that your computer can boot from. Doing that destroys all data that is on the USB-drive! Download the disk-image http://rg42.org/d/a3vtl_20120805-1.img mirrored at linuxaudio.org (preferably download from the linuxaudio.org mirror - it offers better bandwidth and more simultaneous downloads). and write it to a USB-drive – _not_ save it as file _on_ the USB-stick, but write it as disk-image boot from the USB-device Regarding (2.): on GNU/Linux this can be accomplished by various ways. The easiest is probably to use usb-creator (usb-creator-gtk on Ubuntu or Arch-Linux). The canonical way is to use dd on the commandline e.g. if your USB-device is /dev/sdb dd if=/path/to/downloads/a3vtl_VERSION.img of=/dev/sdb This also works on OSX, disk-devices are called /dev/disk1, /dev/disk2, etc instead of /dev/sdb, /dev/sdc,.. although you may prefer to use the Disk Utility GUI. On windows: http://www.pendrivelinux.com/ is the probably the easiest way to write a disk-image onto a USB-key. Persistence The disk-image is a read-only live-system. Every time you boot you will have a pristine system. None of your modifications are saved. In order to retain customizations, you can create a partition with the label 'live-rw' which will automatically be overlaid. The 'live-rw' partition can be on any medium, although it is convenient to keep it on the same disk as the OS. Say, if your USB-drive is 8 GB, you can use the remaining space of 6.5 GB (the live-system is ~1.5 GB) for storage and customizations. Note: the live-rw partition only saves modifications done to the pristine system. It uses a rather smart technique called AUFS to do so. It is not a data-partition per se and can only be used with a live-system of the same version. If you plan to do serious A/V work, store it on an external hard-disk. Getting Started Ardour3 is not [yet] documented. There are bits and pieces of floating around. If in doubt, ask for help via IRC chat. In the $HOME folder, resides an example video for testing <tt>timecode25-test.mov</tt>, that can be loaded as video into Ardour3: Launch Ardour3, create a new session and choose <em>File &rightarrow; Open Video</em> from Ardour's menu… The video-timeline should be pretty much self-explanatory: Menu→Session→Open Video Menu→Session→Export→Video Menu→View→Rulers→Video (or right-click the ruler/marker bar → Video) Menu→View→Video Monitor (xjadeo) Menu→Edit→Preferences→Video Menu→Session→Video maintenance→ … (manual video server interaction) Advanced -- Shell script to create USB drive #!/bin/bash # the disk-device to use: DEVICE=/dev/sdb # or /dev/mmcblk0 or /dev/hdb ,...

As of July 9, 2026, all flavors of Ubuntu 25.10, including Ubuntu Studio 25.10, codenamed “Questing Quokka”, have reached end-of-life (EOL). There will be no more updates of any kind, including security updates, for this release of Ubuntu. If you have not already done so, please upgrade to Ubuntu Studio 26.04 LTS via the instructions provided here. If you do not do so as soon as possible, you will lose the ability without additional advanced configuration. No single release of any operating system can be supported indefinitely, and Ubuntu Studio has no exception to this rule. Interim Ubuntu releases, meaning those that are between the Long-Term Support releases, are supported for 9 months and users are expected to upgrade after every release with a 3-month buffer following each release. Long-Term Support releases are identified by an even numbered year-of-release and a month-of-release of April (04). Hence, the most recent Long-Term Support release is 26.04 (YY.MM = 2026.April), and the next Long-Term Support release will be 28.04 (2028.April). LTS releases for official Ubuntu flavors (not Desktop or Server which are supported for five years) are three years, meaning LTS users are expected to upgrade after every LTS release with a one-year buffer.

MDA.lv2 1.2.12 has been released. This is a port of the MDA VST plugins to LV2. Changes: Avoid over-use of yielding meson options Fix build with MSVC 2022 Fix strict aliasing violation Fix use of uninitialized values in TalkBox Improve const-correctness Remove development symbols from modules by default Use a deterministic and more uniform RNG

Jalv 1.10.0 has been released. Jalv (JAck LV2) is a simple host for LV2 plugins. It runs a plugin, and exposes the plugin ports to the system, essentially making the plugin an application. For more information, see http://drobilla.net/software/jalv. Changes: Add block length command-line parameter for PortAudio Fix PortAudio backend Fix crash with plugins that have non-event inputs Fix stale parameter descriptions in man pages Fully implement fixedBlockLength and powerOf2BlockLength Gracefully handle failure to open audio backend in Gtk interface Update meson fallback subproject wrap files

In 2018 I recreated this blog with an SSG (Static Site Generator) in Python based on pandoc (asciidoctor for older pages), git timestamps and Jinja2 templates. Even though it cached pandoc invocations, building still took too long for my taste and lately I didn’t really feel at ease with modifying…

Geoffrey D. Bennett has just released a major update of ALSA Scarlett GUI, a control program for Focusrite’s Scarlett, Clarett, and Vocaster audio interfaces. DSP control For Vocaster One and Two, Geoffrey added controls for the built-in DSP that includes a pre-compressor filter, a compressor, and a parametric EQ. The controls on the pre-compressor filter and parametric EQ graphs are interactive: you can pick handles and move them around (Q can only be edited numerically though, it seems). You can also choose between 12 filter types: Configuration This is another new window where you can toggle the visibility of unused channels, set stereo linking, and give custom names to inputs and outputs. In addition, you can set the target level for the Autogain feature. For models with larger number of IOs (think Gen4 18i20), this is also where you control monitor groups: Routing window updates There have been some improvements here: Routing lines now display a real-time glow effect that reflects the audio signal level passing through the connection. When a routing connection has a hidden port, there’s an arrow indicator at the visible end now. Adjacent stereo-linked channels are now displayed as a single stereo port. On 4th Gen 16i16/18i16/18i20 interfaces with monitor groups configured, the routing window now shows the effective audio routing. Mixer window updates Just like Routing, the Mixer window got its share of UX/UI updates: Mixer input and output labels now display a real-time horizontal glow bar that reflects the signal level at that port. Gain knobs now include a signal level meter inside the dial (except for Gen1 devices that don’t support it). When channels are stereo-linked, the mixer displays them as a single stereo fader. Presets You can now save and restore presets from the main window. Firmware update changes For the 4gen devices with larger number of IOs, the program now support multi-step firmware upgrade: leapfrog, then ESP, then application. Device support The changes mainly affect the “big 4gen” devices and Vocaster units: Scarlett Big 4th Gen (16i16, 18i16, 18i20) support now includes hardware identification, monitor groups, input mute, and output volume/mute/dim controls. Vocaster interfaces now have dedicated mute controls for speaker and headphone outputs in the main window. For more detailed info, please see release notes.
