Kompresor is a versatile and powerful, yet easy to use, compressor. With several compression algorithms and processing modes under the hood, Kompresor is suitable for use on a wide variety of signals, on the mix bus, or for mastering. For the most transparent compression, ideal for mastering, use AUTO or "AUTO A" envelopes. Use PROGRAM envelope for an easy mix bus gluing effect. If you are after the classic style compression switch to feedback configuration. Select RMS detector for a smoother compression suitable for vocals, guitars, etc. Five processing modes allow you to go from the standard stereo (L/R) compression mode to more surgical modes like compressing the mid (sum) or side (diff) signal only, or compressing exclusively the left or right channel. To help you fine tune compression parameters, enable DELTA feature to monitor only the difference between the uncompressed and compressed signal. Last but not least, Kompresor has an external side chain input for those times when you need to duck one signal based on another one. Features: – Four types of compression Attack/Release envelopes SIMPLE, AUTO, AUTO A, and PROGRAM. – Five processing modes LEFT, RIGHT, MID, SIDE, STEREO – External sidechaining (only in hosts that support external sidechaining) – Very fast attack time - 0.01ms – Ratio up to 30:1 – Soft knee up to 50dB width – Feedforward and feedback configuration – Peak and RMS detectors – Sidechain high pass filter – Parallel processing – Monitoring only the difference between the uncompressed and compressed signal – Intelligent auto makeup gain – 4x oversampling to avoid aliasing – Plenty of factory presets to provide a starting point Kompresor is primarily an AUv3 effect. To use Kompresor as a plug-in, you will need an AUv3 compatible host such as Garageband, AUM, etc. Kompresor application is there to provide a user manual and a chance to use Kompresor with the microphone input. You can try Kompresor on a macOS or a Windows based machine by downloading the demo version of the plug-in (VST3, AUv2, AAX) from our website (https://www.shatteredglassaudio.com) and running it in a DAW of your choice. Sonically speaking there are no differences between the iOS and macOS/Windows versions of Kompresor. ## Key features - Multiple compression algorithms - Five processing modes (stereo, mid, side, left, right) - External sidechain input - DELTA monitoring - Fast attack time (0.01ms) - Peak and RMS detectors - AUv3 plugin compatibility ## Frequently asked questions about Kompresor ### What is Kompresor? Kompresor is a powerful and easy-to-use audio compressor designed for a wide range of signals, including mix bus and mastering. It offers multiple compression algorithms and processing modes to achieve transparent or classic compression styles. ### What are the main features of Kompresor? Key features include four types of Attack/Release envelopes, five processing modes (LEFT, RIGHT, MID, SIDE, STEREO), external sidechaining, very fast attack times, and both peak and RMS detectors. It also includes a sidechain high pass filter and parallel processing. ### How does Kompresor compare to other audio compressors? Kompresor stands out with its versatile processing modes like MID/SIDE compression and its DELTA feature for monitoring compression differences. It also offers a very fast attack time of 0.01ms and a high ratio of up to 30:1. ### What devices is Kompresor compatible with? Kompresor is available for iPhone, iPad, and iPod. It primarily functions as an AUv3 effect, requiring a compatible host like Garageband or AUM. ### How much does Kompresor cost? Kompresor is a paid application, priced at $24.99. There are no in-app purchases or subscriptions for this application. ### Does Kompresor have ads? No, Kompresor does not contain advertisements. It is a premium application focused on providing an uninterrupted audio processing experience. ### How often is Kompresor updated? The latest version of Kompresor is 1.6.1, last updated on November 18, 2025. This indicates a commitment to ongoing development and support for the application. ### What is the age rating for Kompresor? Kompresor has an age rating of 4+. This suggests it is suitable for a wide audience, though its professional audio features are most relevant to adult users. ## Version history (last 5 releases) ### 1.6.1 — 2025-11-18 This version brings: - For multiple choice controls (ENVELOPE, PROCESSING, and CONFIGURATION) you can now select an option from a list of options. The list of options is accessible by tapping on the control. This is in addition to stepping through the options using arrow buttons. In addition to improving the workflow this addition can be beneficial on devices with smaller screens where hitting the arrow buttons may be difficult in the portrait orientation. - Peak input and output meters. - Minor performance enhancements and bug fixes. ### 1.6.0 — 2025-04-02 This version includes a major new feature: a choice of five processing modes. STEREO - The conventional stereo (L/R) compression mode. MID - Compressing only the mid (sum) signal while leaving the side signal uncompressed. SIDE - Compressing only the side (diff) signal while leaving the mid uncompressed. LEFT - Compressing only the left channel. RIGHT - Compressing exclusively the right channel. This version also contains some minor bug fixes. ### 1.2.1 — 2024-08-29 Squashed the bug where the plugin state was not correctly saved and restored. ### 1.2.0 — 2023-10-18 Minor UI improvements. ### 1.1.0 — 2021-11-23 New Features: - Lin/Log detector placement. When Lin is selected the gain reduction is computed, the standard way, based on the Attack-Release envelope of the signal (peak or RMS). When Log is selected, gain reduction in dBs is computed based on the current signal value (i.e. for each sample). Gain reduction values are then smoothed out using the Attack-Release envelope. Using Log setting generally gives a perceptually smoother compression. - Additional envelope. Envelope’s attack and release times are not constant and are computed from the crest factor. ATTACK control sets the minimum attack time. RELEASE control sets the minimum release time. Various bugs were squashed. ## Apps similar to Kompresor | App | Rating | Price | Category | | --- | --- | --- | --- | | [NoLimits2](https://appshunter.io/ios/app/nolimits2/id6470018404) | 5.0 (4) | $12.99 | Music | | [WaveCloud](https://appshunter.io/ios/app/wavecloud/id6471663093) | 4.9 (23) | $7.99 | Music | | [MolliLooper](https://appshunter.io/ios/app/mollilooper/id1622063262) | 5.0 (11) | $8.99 | Music | | [Scissor Hands (Legacy)](https://appshunter.io/ios/app/scissor-hands-legacy/id6479925550) | 4.4 (7) | Free | Music | ## More apps by Shattered Glass Audio - [SGA Phoenix](https://appshunter.io/ios/app/sga-phoenix/id1565520345) - [SGA Eclipse](https://appshunter.io/ios/app/sga-eclipse/id6479641533) - [SGA Phoenix LT](https://appshunter.io/ios/app/sga-phoenix-lt/id6755629174) All apps by Shattered Glass Audio: https://appshunter.io/developer/1565520347 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
