Ableton Live 12.3

Live Suite now features built-in stem separation that runs locally. Any recorded audio material — such as a song, loop, or sample — can be separated into four stems: Vocals, Drums, Bass, and Others. The Others stem includes all parts of the audio that are not recognized as vocals, drums, or bass. You can separate audio files from the browser or separate clips from the Session or Arrangement View. To do so, right-click a sample in the browser or a clip in Session or Arrangement View and select Separate Stems to New Audio Tracks. Each stem is rendered onto its own track in a new Group Track. Any audio effects from the source track are also added to the Group Track. The clip used for separation is muted to avoid doubled output. You can choose between two quality modes for the separation: High Speed and High Quality. The mode determines whether the separation process prioritizes quickness or accuracy. In High Speed mode, all stems are separated in a single pass, so the process will be faster, though it may still take several minutes on older system configurations. In High Quality mode, the separation accuracy is improved (as measured by a higher Signal-to-Distortion Ratio, i.e., SDR score), at the cost of slower processing. The Vocals, Drums, and Bass parts are processed through their own dedicated separation passes. The Others stem is then created from the remaining audio after the three passes. Generally speaking, the overall amount of time required for the separation process highly depends on your system configuration. Stem separation may take a while on older Windows computers, Intel Macs, and Mac computers running macOS 11 Big Sur. Due to an incompatibility issue, stem separation will also run slowly on Apple Silicon computers with macOS 26.1 Tahoe. Splice - the industry's leading sample library - is now integrated into Live's browser. Anyone with a free or paid Splice account can access their library, browse, preview, and download samples directly within Live. You can browse and save samples to your Splice library, as well as preview Splice samples in sync with Live's transport. When you find a sample you like, you can drag it from the Splice label into the Session or Arrangement View. Alternatively, you can double-click the sample name or press the Enter key to load the sample into a Set. Imported samples are saved to the User Library → Samples → Splice folder by default. You can update this location to the Current Project folder or a custom folder using the Download Folder for Splice Samples option in Live's Library Settings. In addition to searching for samples, you can have Splice find samples that would fit with existing material in your Set. To do so, make a clip or time selection within Session or Arrangement View, then click the Search with Sound widget in the Home tab of the Splice label. Splice will then find and display complementary samples based on the style and rhythm of the selection. The Key filter in the sample categories within Splice includes an "Apply Key from DAW" option, which automatically detects the scale root and name set in Live's transport bar when Scale Mode is active. You can use this option to constrain search results to the detected key and scale. Note that only major and minor scales are supported with this option. You can also use the Transpose option in the Splice Preview settings to set different transpositions for sample playback within the Splice label or sync the Splice Preview to the Set's key.
