Web based Sample Slicing Utility

brian3kb

Updated to v1.4.9

Lots of under the hood changes, bugfixes, and for macOS, the Command key is now mapped to Control key keyboard shortcuts, so all keyboard shortcuts are available to Mac users 😀

Sessions now persist between page refreshes, and the audio export target has been decoupled from the working sample rate, allowing exports to differing sample rates without clearing out the current list.

Full list of changes:

• Store list in indexedDb for optional restoring of the last session on next load.
  • Map the Ctrl key to the Cmd key for macOS keyboard shortcuts.
  • Automatically ignore empty or nonsense cue markers (e.g. zero length or start/end greater than file length, end greater than start).
  • Improve handling of joining chains with other chains/files and slice types.
  • Normalize the slice-type to the common format when processing internally.
  • Show the number of slices if the file has any on the slice-grid icon instead of OT/DC/OP text.
  • Improved the speed of conversion between spaced/none-spaced chains from the slice panel.
  • Allow users to change audio context when files are loaded without emptying list; An advisory message to confirm the action is shown, as the sample rates of all files in the list are internally resampled to the new context.
  • Decoupled the working audio sample rate from the export audio sample rate. This allows users to work at 44.1kHz, but export to 48kHz for example without destructively resampling the list source buffers.
  • Audio context options are now an audio config panel, allowing arbitrary sample rates, and choice of bit depth and channel combinations.
  • A list of common configurations by hardware name are available in the audio config panel.
  • Audio config panel has slice grid options inputs so last used values are remembered. These values are also updated as part of the common configs list options.
  • 'Retain session data between browser refreshes?' setting on settings panel.
  • Gain adjustment on the edit panel (Thanks to eljeff).
  • Option in settings panel to download single files when Shift+Clicked to prevent accidental downloads being triggered.
  • Added rough stretch to selected actions list, this attempts to retain pitch while doubling the duration of the sample.
  • Importing of Polyend Tracker (OG) .pti instrument files (mono only).
  • Toggle slice looping from the slice panel (useful for .ot exports).
  • Toggle file looping point from the slice panel (useful for .ot exports).
  • Correctly calculate the tempo and bar values on .ot exports.
  • Create .ot button on slice panel to create a .ot metadata file independently of downloading of the audio file.

Ohhhh myyyy this is amazing!. So excited for this!. Making chains for the Digitakt has always been such a pain. Truly amazing piece of work. It’s superb, the UI is excellent too. Kudos @brian3kb , you’re a star.

How did I miss this?. Mind blown on every level. Foremost is that it’s an amazingly useful tool that encapsulates a ton of features I always wanted and had tedious workarounds for. The UI and usability is excellent, and it works on the iPad, and you can drag and drop and, and…
Secondly, we get to check out the code!. When I’m not being an ABF rock and roll star I work in web apps. I’m ashamed to admit I had no idea this was possible with JavaScript. Just amazing. Also, this app is “plain” JavaScript, beautifully written code. Such a great learning source. @brian3kb is the man of the moment.

Coincidentally, for the past days I’ve been stuck in a Shortcut (app) script to join audio samples into chains. I used to do this with SampleCrate but the process is too manual and takes too long when you want to convert a drum kit library with velocity layers into sample chains. The script I’m adapting connects to a-she’ll app, uses ffmpeg python and due to all these back and forth it’s quite buggy and cumbersome. Also missing the essential and superb “Spaced Chain” feature and many other.
Would the Shortcuts app be able to run an adaptation of this JavaScript?. As an api of sorts… why would you want that?. For direct integration with files app (select multiple, right click - chain).

Thanks for the kind words @tahiche!

I have not created any web manifest shortcuts for DigiChain, but its something I could take a look at, last I checked though, they didn't allow passing of attached data; my daily driver is a Windows machine, so not used Automator/Shortcut in quite a few years, unsure how well web manifest shortcuts work via that tool as at the moment, shortcuts from the manifest are experimental in browsers (and not currently implemented in Safari) - I have a feeling this would require a proper desktop app to handle the OS API's to facilitate access to the local files, PWA's are somewhat more restrictive in these aspects, more so on Apple OS's.

v.1.4.12 released to main

• Added Double selected action to add a copy of a sample to the end of itself for the selected samples.
• Prev / Next buttons on the edit panel to navigate between samples without needing to close the edit panel and re-select from the list.
• Cleaned up selected actions list, added overflow so list can scroll on mobile and flex to the width of the panel.
• Shift + Ctrl/Cmd click stretch longest/shortest selected action to set the stretch length in samples instead of seconds.
• Shift + Click on Trim Right button in editor, or selected actions, to also trim silence from the start (left) of the sample.
• Changed the behavior of the grid size buttons, clicking will now set the grid size and keep the selection, to also change the selection is now the shift+click action; This is inverted from other versions, but has been a requested change by several users.
• Shift + L will toggle the lists visibility, useful for simple chaining/conversion if loading a large number of files that can cause the browser dom rendering to slow.
• Hide 'Create .OT' button on sample panel if target SR is not 44100.
• Added common configuration for Digitakt II.
