# Practice Player third-party notice manifest

Practice Player is built with JUCE 9.0.0 under the applicable commercial JUCE
license or another valid JUCE licensing option selected by Arntz Labs. The JUCE
framework is not licensed to Practice Player users under this freeware EULA.
JUCE licensing details are available at <https://juce.com/legal/juce-9-licence/>.

Release packaging includes the complete license text and required attributions
for every component present in the released binary. Byte-for-byte copies from
the pinned JUCE 9.0.0 source tree are stored in `Legal/Licenses/`; the macOS and
Windows packaging scripts verify their SHA-256 hashes before creating a public
package. This manifest records the current audit and accompanies those texts.

## Standalone application dependencies

  Foundation.
- Ogg Vorbis — BSD-style license; copyright Xiph.org Foundation.

- Signalsmith Stretch — MIT license; copyright 2022 Geraint Luff / Signalsmith

JUCE's ASIO integration is disabled by default in this project
(`JUCE_ASIO=0`), so the proprietary Steinberg ASIO SDK must not be enabled in a
Windows release unless Arntz Labs first completes the applicable Steinberg
license process and updates this manifest.

## Format-specific dependencies

- VST3: Steinberg VST3 SDK, MIT license; copyright Steinberg Media
  Technologies GmbH.
- Audio Unit: Apple AudioUnitSDK, Apache License 2.0.
- AAX: Avid AAX SDK and PACE signing components, under their applicable
  proprietary agreements. The production AAX release must receive a separate
  notice and license review after the final Avid/PACE toolchain is established.

## Release checklist

Before publishing a download:

1. Generate the release from the pinned dependency versions.
2. Copy the exact dependency license texts from that source revision into the
   installer or an accompanying `Licenses` directory.
3. Confirm that build flags did not introduce additional codecs, SDKs, network
   libraries, copy-protection components, or installer dependencies.
4. Re-run this audit independently for macOS and Windows and for Standalone,
   AU, VST3, and AAX packages.
