Boom 3D vs SotF

Boom 3D is an audio enhancement app for Mac and Windows, with virtual surround sound, equalization, and playback controls. Its 3D surround effect works with headphones and includes controls for LFE gain and audio intensity. Both desktop versions include a 31-band equalizer with genre presets, while system-wide volume boosting is available only on Mac. A controller can set levels separately for running applications. The built-in player handles locally stored audio and playlists, and the app provides access to more than 20,000 internet radio stations across 120 countries. It can work offline, though radio and updates require internet access. The product page lists a 15-day free trial that does not require payment details. The paid product starts at ₹925.37, and one license activates on up to four devices across platforms. The site also lists Chrome and Safari extensions. Global Delight, founded in 2007 and headquartered in Udupi, India, makes the app. Separate help pages and manuals are available for Mac and Windows.

SotF is a free, open-source audio player and optimizer for room and headphone sound, available for Linux, macOS and Windows. It plays FLAC, MP3, AAC, ALAC and Vorbis files, and lists more than 40 audio plugins for equalization, compression, limiting, upmixing, binaural processing, convolution and denoising. Room EQ analyzes room response and calculates correction filters for a plugin chain; using it requires a measurement microphone, its calibration file and connected speakers. Headphone EQ calculates parametric filters targeting the Harman curve for hundreds of measured headphone models. Spinorama EQ provides correction for thousands of speakers without a microphone. SotF can export settings for CamillaDSP, Equalizer APO, EasyEffects, Wavelet, PipeWire and Roon. On macOS, a CoreAudio HAL virtual device can route audio from other apps through a configured plugin chain. The app runs on the user’s machine and says it does not collect user data or listening history. Speaker EQ queries the public Spinorama API for the selected model. SotF is GPL-3.0 licensed and has no subscription.
