Remove vocal for karaoke (not hip) Isolate vocal for remixing/mash-ups (way hip) Sophisticated FFT & cepstral algorithms, not "left minus right"Back in the old days you could remove the vocal from a stereo track by subtracting the left channel from the right. You only got mono output, The bass was missing, The mix sounded terrible, You could only remove the vocal, not isolate it, It only really worked on old tracks, before they started using stereo reverb.Voice trap offers two sophisticated DSP algorithms: FFT-based center channel suppression / isolation, Cepstral liftering (an advanced technique that can identify harmonically rich elements in a mix).Together these allow Voice Trap to overcome those problems: The output is stereo, The bass frequencies are left untouched, The mix is largely preserved, You can choose to remove the vocal OR isolate it, Good results possible on some modern tracks (ie, with stereo reverb).Voice Trap 2.0b Requirements:

GrapheneOS also supports generic targets, but these aren't suitable for production usage and are only intended for development and testing use. For mobile devices, the generic targets simply run on top of the underlying device support code (firmware, kernel, device trees, vendor code) rather than shipping it and keeping it updated. It would be possible to ship generic system images with separate updates for the device support code. However, it would be drastically more complicated to maintain and support due to combinations of different versions and it would cause complications for the hardening done by GrapheneOS. The motivation doesn't exist for GrapheneOS, since full updates with deltas to minimize bandwidth can be shipped for every device and GrapheneOS is the only party involved in providing the updates. For the same reason, it has little use for the ability to provide out-of-band updates to system image components including all the apps and many other components.
Devices need to be meeting the standards of the project in order to be considered as potential targets. In addition to support for installing other operating systems, standard hardware-based security features like the hardware-backed keystores, verified boot, attestation and various hardware-based exploit mitigations need to be available. Devices also need to have decent integration of IOMMUs for isolating components such as the GPU, radios (NFC, Wi-Fi, Bluetooth, Cellular), media decode / encode, image processor, etc., because if the hardware / firmware support is missing or broken, there's not much that the OS can do to provide an alternative. Devices with support for alternative operating systems as an afterthought will not be considered. Devices need to have proper ongoing support for their firmware and software specific to the hardware like drivers in order to provide proper full security updates too. Devices that are end-of-life and no longer receiving these updates will not be supported.
Broader device support can only happen after the community (companies, organizations and individuals) steps up to make substantial, ongoing contributions to making the existing device support sustainable. Once the existing device support is more sustainable, early research and development work for other devices can begin. Once a device is deemed to be a worthwhile target, the project needs maintainers to develop and maintain support for it including addressing device-specific issues that are uncovered, which will include issues uncovered in the device support code by GrapheneOS hardening features.
GrapheneOS aims to provide reasonably private and secure devices. It cannot do that once device support code like firmware, kernel and vendor code is no longer actively maintained. Even if the community was prepared to take over maintenance of the open source code and to replace the rest, firmware would present a major issue, and the community has never been active or interested enough in device support to consider attempting this. Unlike many other platforms, GrapheneOS has a much higher minimum standard than simply having devices fully functional, as they also need to provide the expected level of security. It would start to become realistic to provide substantially longer device support once GrapheneOS controls the hardware and firmware via custom hardware manufactured for it. Until then, the lifetime of devices will remain based on manufacturer support. It's also important to keep in mind that phone vendors claiming to provide longer support often aren't actually doing it and some never even ship firmware updates when the hardware is still supported by the vendors...
Examples of the global OS configuration available to apps are time zone, network country code and other similar global settings. Per-profile examples are dark mode and language. Similar to extension and browser configuration / state being fingerprinted by web sites, an app could use a combination of these things in an attempt to identify the installation. All of these things vary at runtime and can be changed, but some are fairly unlikely to change in practice after the initial setup of the device such as the ones listed above. GrapheneOS will likely add further restrictions in this area and a couple toggles for certain cases like time zones to use a standard value instead.
Connectivity checks designed to mimic a web browser user agent are performed by using HTTP and HTTPS to fetch standard URLs generating an HTTP 204 status code. This is used to detect when internet connectivity is lost on a network, which triggers fallback to other available networks if possible. These checks are designed to detect and handle captive portals which substitute the expected empty 204 response with their own web page.
The connectivity checks are done by performing an empty GET request to a server returning an empty response with a 204 No Content response code. The request uses a standard, frozen value for the user agent matching the same value used by billions of other Android devices:
In some cases, licensing is also an issue. GrapheneOS is permissively licensed and is usable for building devices with an immutable root of trust. GPLv3 is deliberately incompatible with these kinds of locked down devices, unlike GPLv2 code such as the Linux kernel. This means GrapheneOS can't include GPLv3 code without forbidding use cases we want to support. GPLv3 is no problem for our own usage, but we don't want to forbid using GrapheneOS as a replacement for the Android Open Source Project in locked down devices.
Yes, the GrapheneOS code is reviewed by external security researchers, companies and organizations on a continuous basis. This is the main benefit of GrapheneOS being an open source project actively used by other organizations, but it is certainly not something to take for granted based on a project being open source. We put a lot of work into making our code well documented and easy to review. Auditing and code review cannot be done properly as a one time thing but rather need to be done continuously as the code changes. Most of the code review and auditing results for GrapheneOS can be seen from the public pull requests and issue trackers. For example, the French ANSSI organization uses a bunch of our work and has given us suggestions along with reporting issues including a couple issues in hardened_malloc where it could have a false positive detection of memory corruption and wrongly abort the process.[1][2] We've built relationships with security researchers and organizations interested in GrapheneOS or using it which results in a lot of this kind of collaboration. This is not a one-time event but rather something that happens regularly as the code evolves, features are added and we ported to new release. The benefits of a group unfamiliar with the code spending a short time doing a shallow review are greatly overstated in marketing. We instead focus on having people very familiar with areas of the code regularly auditing all our changes. The large number of upstream Android security vulnerabilities discovered by GrapheneOS despite us not actively seeking them out speaks to the results of our review and testing. 2ff7e9595c
