• P2P network search. The system performs simultaneous queries across multiple peer-to-peer protocols, displaying consolidated results with detailed information about available sources, transfer rates, and file metadata. The search includes filters by format, audio quality, and number of active sources.
• Multisource download. The technology allows obtaining file fragments from different network nodes simultaneously, optimizing transfer speed through parallel connections. The system verifies data integrity during the process and automatically repairs corrupted segments.
• High-resolution player. Playback component supporting lossless audio formats including FLAC, ALAC, WAV, and compressed formats like MP3, AAC, OGG. It implements digital signal processing with resolution up to 32-bit/384kHz.
• Library organization. Automatic cataloging system that analyzes ID3 metadata, Vorbis Comments, and directory structure. It classifies content by artist, album, genre, release year, and play frequency, generating customized views.
• Spectral analysis. Diagnostic tools displaying spectrograms, waveforms, and real-time frequency analysis. Provides dynamic range measurements, clipping detection, and transcoding quality assessment.
• Library sharing. Module allowing publication of music collection selections on the peer-to-peer network, with granular control over shared files and availability statistics. Configures access levels and availability periods.
• Device synchronization. Mechanism for replicating libraries and playlists across multiple software installations. Maintains consistency of metadata, playback progress, and ratings across all linked devices.
• Advanced tagging. Metadata editor with support for standard and custom fields, including album art, song lyrics, and composer information. Performs batch correction and automatic retrieval from music databases.
• Usage statistics. Tracking system that records play metrics, music preferences, and download patterns. Generates reports on most listened-to artists, genre distribution, and temporal evolution of habits.
• Format conversion. Transcoding module that transforms files between different audio codecs, maintaining or adjusting quality parameters according to predefined settings. Preserves metadata during the conversion process.
• Priority management. Intelligent queue system that organizes downloads based on availability criteria, speed, and user preferences. Dynamically allocates bandwidth resources based on defined urgency.
• Network monitoring. Control panel displaying connection activity, active nodes, incoming/outgoing traffic, and status of P2P protocols. Provides alerts on connectivity interruptions and transfer performance.
• Backup and archiving. Backup functionality that preserves library structure, metadata, and playlists. Implements versioning schemes and recovery from data loss.
• Content filtering. Exclusion mechanisms based on quality criteria, format, geographic origin, or specific metadata. Applies automatic rules to discard unwanted results during searches.

Development of Sonosano began in 2025 as a personal project focused on preserving music files in high-fidelity formats. The application was created by a small team of developers specializing in digital signal processing and network technologies. The technical implementation uses C++ for low-level components, Python for task automation, and Qt for the graphical interface. The software architecture incorporates specialized audio libraries and custom implementations of peer-to-peer protocols.
