Z-LiveRec V2.25 launched!

V2.25 2022-04-18 – NEWS!

I must first confess that development always takes 4 times more than expected. But here you have a new fresh version of Z-LiveRec – The multitrack recorder for Raspberry PI! In this new version you will find many nice improvements and also some new nice tools and functions that will make Z-LiveRec to the Virtual Soundcheck Tool #1 for your digital mixer!

Have a look – and please check the new version out!

  • Feature to change the ”Quit” button to not only quit the application – but also added the function to able to completely shutdown the Raspberry PI OS. This features can be turned “on” in the License dialogue window and by checking the Quit Button option.
  • Added keyboard shortcuts ctrl + r(recording), p(playing), s(stop), x(quit app), (and F1, F2, F4 and F10 – see below)
  • Added more buffer sizes – smaller size 131072 and bigger sizes 4194304 – to try with if buffer overruns show up and when using slower USB Sticks.
  • Fixed so that sound files can be played/read from any sub directory. Recordings will still only be stored in the root of the selected storage device. (Except when exporting recordings)
  • Added a file split counter in the GUI when recording in *.wav type of files. (2 GB splits)
  • Virtual Soundcheck & Export tools – Added locators in the GUI. When in play mode – the new Virtual Soundcheck & Export tools shows up with some new buttons. Left & right locator will set play area of an existing recording. Pressing “Play” will replay the recording between the locators. Pressing “loop” will keep playing the selected area between the locators forever. (Keyboard shortcuts are also added to set left/right locator by pressing ctrl F1 and ctrl F10. Ctrl F2 will start playing between the locators. Ctrl F3 will turn on ”loop” replay – Ctrl F4 will turn off loop replay)
  • Virtual Soundcheck & Export tools – by pressing “export” when replaying sound files in locator mode – the selected area between the locators can be exported to a new wave file. (This can be done from any file format like *.wav, *.W64 or *.caf and these can be exported to *.wav format. The exports can be done to both to a single multitrack file or be split by channel to separate wav files. See button “Separate tracks”) This function is extremely useful when been recording a complete concert with 32 channels and you want to export a part, song to a new separate file. By splitting all channels to separate files – any DAW on the market can be used for post-production tasks.
  • Virtual Soundcheck & Export tools – when in main window – an export function is available to export a complete recording from any file format like *.wav, *.W64 or *.CAF to *.wav format – both to a single multitrack file or been split by track/channel to separate wav files. See button “Separate tracks”. Note – Free storage space is needed on the same drive as the original file.

Performance and bug fixes:

  • Added some performance tweaks and fixed some hangs ups bugs.
  • Memory management using a garbage collector function to clean up the system after playing/recording – reports and stats can be found in the logfile.
  • Logging of CPU version and OS version when recording/playing in the Z-LiveRec.log.
  • Fixed a bug when in touch mode when the USB devices were more than 3, all devices did not report. Same with storage devices.
  • Hard test of doing large recordings – up to 64GB – without any problems or GUI shutdowns. Works great in Raspberry PI OS – 32bit Bullseye.
  • GUI clean up in the main screen/window.
  • Launched 64 bit support for Raspberry PI OS – Bullseye – this is delivered as a separate application – available to download for registered users of Z-LiveRec. Note: This version is still for experimental uses. (Please note: a 64 bit application will not run in a 32 bit OS and vice versa – and the auto update function will currently not work.)

Some Other notes

  • An USB Stick must have a proper set label name – before use with Z-LiveRec. (When using default or none label – errors will otherwise occur when recording)
  • Verified that 2GB wave splits (when using *.wav to not violate the format) does not generate any delay between splits. Checked and verified in Cubase 11 – no delays found between files.
  • If experiencing many buffer overruns problems when using exFAT and doing recordings with W64 and with many channels – a too slow USB stick could be the root cause. It looks like changing to NTFS file format can improve the situation. Another recommendation is to use Sandisk Extreme Go USB 3.2 Flash drives with 64GB – which has a read speed of 395 MB read/s and a write speed of 100 MB/s. Compared to the Sandisk Ultra Slim Fit – which has a read speed on 150MB/S and a write speed on 55MB/S – the Extreme GO USB stick can improve the situation with experienced buffer overruns a lot! (e.g Zero overruns!)
  • More details about Z-LiveRec 2.25 can be found in the manual for V2.25

A free update is available for registered users (Login to “My Account” and download the latest edition or use the e-mail download link from the original order acknowledgement) and free demo/trial version is also available for everybody else to try the app!

Please note: Using the auto update function in Z-LiveRec (for registered users) – You will find a zip file in the PI/Home directory – and you can just extract the zip file yourself – and the V2.25 version will show up.

The update process will try to unzip Z-LiveRec and overwrite the old version of the app – and a chmod r+x command can be required to get the V2,25 version to run again. See the manual for more information.
