In order to record sound in Sprunki, one must make use of its own “Multi-Track Studio” feature with as many as 32 synchronous tracks of recording (resolution 48kHz/24-bit), each of which supports loading the VST3 plugin (up to 98% compatibility). As an example, user “SoundCrafter” has recorded electronic track “Neon Pulse” via Sprunki’s analog model synthesizer (parameter: filter cut-off frequency 2200Hz, Q value of resonance 0.7). The play count of the single was more than 800,000 times, and the revenue share of the creator was $3,200. During recording, one must maintain the peak input level between -6dB and -3dB (dynamic range 114dB), and the total harmonic distortion (THD) less than 0.005% in order to avoid clipping distortion.
Hardware configuration-wise, Sprunki is compatible with ASIO drivers (latency ≤2.1ms), and it is advisable to utilize professional sound cards (like Focusrite Scarlett 18i20), whose ADC/DAC signal-to-noise ratio is up to 120dB. 2023 tests revealed that while recording human speech using the Rode NT1 microphone on the XLR interface, the background noise level was -129 DBV, and the error of the frequency response curve was ±0.8dB (20Hz-20kHz). If a MIDI keyboard (e.g., Arturia KeyLab 61) is being used, the note triggering accuracy error is as low as ±0.3ms, and the actual real-time force-sensing response curve can be customised and calibrated (light tap force threshold is 20g, and heavy tap is 150g).
While recording together, Sprunki’s cloud collaboration module enables five users to edit the same project simultaneously in real time (data synchronization speed 12MB/s), and median global server latency is 92ms. For example, global band “EchoSphere” recorded “Global Harmony” within 3 days using this feature. The guitar, bass and drum kit were remoted recorded by United States, Brazilian, and Japanese musicians respectively. The last remix file (WAV 96kHz/ 24-bit) is 1.2GB in size. The multi-track phase error was compressed to ±0.7ms through the AI alignment algorithm.
The post-processing tools are:
Smart noise reduction: It can eliminate background noises of -45dB (such as air conditioning noises) without compromising the clarity of human speech (STOI score 0.92).
Automatic pitch correction: Based on the Melodyne algorithm, the accuracy of the pitch correction is ±2 minutes (normal mode) or ±0.5 minutes (professional mode).
Master processing: Incorporated iZotope Ozone module for loudness standardization up to -14 LUFS, and 23% width expansion of the stereo field.
User “MixMaster” used these utilities to boost the dynamic range of the single from 10dB in the original recording to 16dB, and the play volume on the streaming media site increased by 57%.
Regarding compliance and copyright management, Sprunki’s blockchain evidence storage system can generate a one-of-a-kind NFT identifier for a work within 3 minutes (with a hash value length of 256 bits), and the cost of copyright registration is 0.99 per instance (50+ for conventional channels). In 2023, electronic musician Luna released the “Digital Dawn” sound pack via the built-in market of the service (29.99), with sales totalling more than 6,200 copies, after 1515,570 deductions. Free users have an option to export up to 3 lossless format creations per month. Upon subscription to the Pro account ($14.99/month), the Dolby Atmos panoramic mastering feature (with 9.1.6 channels of support) is enabled. User research shows that the average monthly creation volume of paying members is 3.2 times higher than that of non-members.
Troubleshooting exercise: When lagging behind happens during recording, check the buffer Settings (a recommendation is using 256 samples, CPU usage rate ≤22%) and terminate background unnecessary applications (such as web browsers for freeing up 1.2GB of memory). The practice in 2022 shows that after optimizing system Settings, the success rate for real-time recording of the AMD Ryzen 9 5900X device’s 32-track project increased from 78% to 99%.
