In Sprunki, users are enabled to make music with its incorporated “Digital Audio Workstation (DAW)” module. This module offers a 128-track sequfier, over 50 virtual instruments (synthesizers and drum machines), and 1,200 pre-set sounds. For example, in 2023, the song “Stellar Pulse” by user “ElectroMaster” using Sprunki’s FM synthesizer (parameters: carrier frequency 800Hz, modulation index 4.2) had over 500,000 plays on the website, and the revenue share was $2,500. Technically, the audio engine provides 24-bit /96kHz high-definition recording, and features an SNR of 112dB and a total harmonic distortion (THD) of less than 0.003%, which is better than the industry standard of 0.008%.
During the creative process, Sprunki’s composition module enables its AI to generate four stylized renditions (e.g., electronic dance and jazz) of the melody fragments input by the user (where the number of MIDI notes ≥8) at a mean generation speed of 0.8 seconds per time, with an accuracy rate (in line with user expectations) of 78%. During the 2022 Berlin Electronic Music Festival, producer Lena utilised this ability to complete a 3:45 competition track in 37 minutes, improving efficiency by 63% over traditional DAW. The rhythm synchronisation algorithm can sync multi-track audio (with an error of ≤±2ms) automatically and enable real-time variable speed from 60-200 BPM. User “BeatHacker” increased the impact of the chorus part of the single “Chaos Theory” by 29% with the dynamic variable speed feature.
Collaboration process is a feature – Sprunki’s cloud collaboration platform can have a maximum of 10 people edit the same project at the same time, with a data synchronization rate of 12MB per second (compression ratio of 85%) and delay controlled within 150ms. In 2023, multinational companies “SoundWave Collective” released the album “Global Fusion” with this function. The total number of downloads amounted to more than 120,000 times, and the total number of shares to the creators amounted to $18,000. Of these, the drum band version of the leading single “Neon Horizon” was live-recorded by Brazilian, Japanese, and German artists, with the cross-time zone collaboration failure rate being a record low of just 0.4%. The platform also features intelligent copyright management (blockchain proof of existence storage), with a unique NFT hash value assigned to each work of art. The confirmation time has been reduced from the 72-hour industry norm to 9 minutes.
Hardware compatibility-wise, Sprunki supports the MIDI 2.0 protocol and can be connected to more than 200 external device types (e.g., Akai MPC Live II, Novation Launchkey). Latency tests show that: When transmitting MIDI signals through the USB 3.0 interface, response time is 1.2ms (average of similar software is 3.5ms). User “StudioPro” performed the piano part on the Roland FA-08 keyboard. Employing Sprunki’s physical modeling technology (with a PCM sampling library capacity of 32GB), the tineal properties of the Steinway D-274 were emulated, and dynamic range was 98dB (102dB for a real piano).
The economic model encourages creation – Sprunki’s “Creator Market” allows creators to sell sound packs (4.99-29.99), with the company taking a 15% commission (lower than the industry norm 30%). As of 2023, the top-selling sound pack Cyberpunk Drums sold 8,400 copies and the creators earned 21,000. Free users can export 3 full tracks (WAV/MP3) per month. After they subscribe to the Pro plan (9.99/month), they can export unlimited and get access to the Dolby Atmos panoramic sound mixing feature. As a result, the user retention rate has increased to 67% (only 28% for free users). Educational institutions such as Berklee College of Music have integrated Sprunki as an educational tool. The annual number of student productions has increased by 41%, 12% of which have been included on the official Spotify playlist.
