| title: 'Search Mode', | |
| body: ` | |
| <h4>Vector Similarity (recommended)</h4> | |
| <p>Uses AI embeddings to find tracks by <em>meaning</em>, not just keywords. Your query is converted into a vector and compared against pre-computed embeddings of each track's metadata. This finds semantically similar results even if the exact words don't match.</p> | |
| <p>Example: searching "happy summer vibes" will find tracks tagged as "upbeat", "cheerful", "sunny" etc.</p> | |
| <h4>BM25 Text</h4> | |
| <p>Traditional keyword-based text search (like a search engine). Matches exact words and scores by term frequency. Best when you know the exact tags or words you're looking for.</p> | |
| <p>Example: searching "lo-fi hip hop" matches tracks that literally contain those words.</p> | |
| <h4>Combined</h4> | |
| <p>Runs both Vector and BM25 searches and merges the scores. Useful when you want both semantic understanding and exact keyword matching.</p> | |
| <h4>Music Similarity</h4> | |
| <p>Search by audio fingerprint. Upload an audio file or click "Find Similar" on any result to find tracks that sound alike. Uses Whisper encoder embeddings that capture the audio characteristics of each track.</p> | |
| ` | |
| }, | |
| vector_field: { | |
| title: 'Vector Search Field', | |
| body: ` | |
| <p>Choose which text field's embeddings to search against. Each field captures different information about the track:</p> | |
| <h4>Whisper Caption (recommended)</h4> | |
| <p>AI-generated description of what the music <em>sounds</em> like (instruments, genre, mood, tempo, structure). Generated by the Music-Whisper model that listens to the actual audio. This is the most descriptive field and works best for natural language queries.</p> | |
| <h4>Tags</h4> | |
| <p>Genre and style tags from the source platform (e.g. "electronic, ambient, chill"). Good for genre-specific searches.</p> | |
| <h4>Lyrics</h4> | |
| <p>The lyrics text from the source metadata (not ASR). Searches against the original lyrics provided by the creator. Only available for ~53% of tracks.</p> | |
| <h4>Mood</h4> | |
| <p>Mood/emotion tags (e.g. "melancholic", "energetic", "peaceful"). Only available for Mureka tracks (~42% of dataset).</p> | |
| <h4>Transcription</h4> | |
| <p>Speech-to-text transcription from the Parakeet ASR model. Searches what was actually <em>sung or spoken</em> in the audio. Available for ~57% of tracks (vocal tracks only).</p> | |
| ` | |
| }, | |
| bm25_field: { | |
| title: 'BM25 Text Search Field', | |
| body: ` | |
| <p>Choose which text field to run keyword search on:</p> | |
| <h4>Whisper Caption</h4> | |
| <p>Search the AI-generated music descriptions. Good for finding specific instrument mentions, tempo descriptions, etc.</p> | |
| <h4>Tags</h4> | |
| <p>Search the genre/style tags. Use commas or spaces between terms.</p> | |
| <h4>Transcription</h4> | |
| <p>Search the ASR transcription text. Find tracks by specific words that were sung.</p> | |
| <h4>Lyrics (hashed)</h4> | |
| <p>Privacy-preserving search of original lyrics. Tokens are HMAC-hashed, so you need to search with the exact same words. Partial matches may not work as well.</p> | |
| ` | |
| }, | |
| rank_by: { | |
| title: 'Ranking Method', | |
| body: ` | |
| <p>After retrieving matching tracks, results are sorted by:</p> | |
| <h4>Relevance</h4> | |
| <p>The default. Sorts by search score (cosine similarity for vector search, BM25 score for text search). The most relevant results appear first.</p> | |
| <h4>Music Similarity</h4> | |
| <p>Re-ranks results by audio similarity using Whisper encoder embeddings. Useful to cluster sonically similar tracks together.</p> | |
| <h4>Aesthetics Score</h4> | |
| <p>Sorts by a composite quality score (0-5) computed from coherence, musicality, memorability, clarity, and naturalness. Higher scores indicate higher perceived quality.</p> | |
| <h4>Play Count / Like Count</h4> | |
| <p>Sort by popularity metrics from the source platform. Play count = total listens, Like count = upvotes/hearts.</p> | |
| ` | |
| }, | |
| top_k: { | |
| title: 'Number of Results (K)', | |
| body: ` | |
| <p>How many results to retrieve from the search index. Higher values take longer but give more results to filter and browse.</p> | |
| <ul> | |
| <li><strong>20-50:</strong> Fast, good for quick exploration</li> | |
| <li><strong>100-200:</strong> Thorough search, good balance</li> | |
| <li><strong>500-1000:</strong> Deep search, useful with strict filters</li> | |
| <li><strong>5000-10000:</strong> Exhaustive, use with filters to narrow down</li> | |
| </ul> | |
| <p>Note: The actual number of displayed results may be less than K after applying filters (subset, vocal, duration, etc.).</p> | |
| ` | |
| }, | |
| stage2: { | |
| title: 'Stage 2 Refinement', | |
| body: ` | |
| <p>Stage 2 lets you apply a <em>second</em> search query to re-rank Stage 1 results. This is a powerful two-step filtering approach:</p> | |
| <h4>How it works</h4> | |
| <ul> | |
| <li><strong>Stage 1:</strong> Your main query retrieves a broad set of candidates</li> | |
| <li><strong>Stage 2:</strong> A second query re-scores those candidates, and only the top matches are returned</li> | |
| </ul> | |
| <h4>Example use cases</h4> | |
| <ul> | |
| <li>Stage 1: "electronic music" (by tags) → Stage 2: "dark atmospheric pads" (by caption)</li> | |
| <li>Stage 1: "rock guitar" (by caption) → Stage 2: "love song" (by transcription)</li> | |
| </ul> | |
| <p>This combines different search strategies for precision that a single query can't achieve.</p> | |
| ` | |
| }, | |
| stage2_detail: { | |
| title: 'Stage 2 Configuration', | |
| body: ` | |
| <p>Configure how the second stage works:</p> | |
| <h4>Mode</h4> | |
| <p>Choose Vector Similarity or BM25 for the second-stage query. You can mix modes (e.g. BM25 in Stage 1, Vector in Stage 2).</p> | |
| <h4>Vector / BM25 Field</h4> | |
| <p>Choose a different field for Stage 2. A common pattern is to search by tags in Stage 1 and refine by caption in Stage 2.</p> | |
| <h4>Stage 2 K</h4> | |
| <p>How many of the Stage 1 results to keep after re-ranking. A lower value gives more precision, a higher value gives more recall.</p> | |
| ` | |
| }, | |
| negative: { | |
| title: 'Negative Prompt', | |
| body: ` | |
| <p>The negative prompt lets you <em>exclude</em> certain characteristics from your results.</p> | |
| <h4>How it works</h4> | |
| <p>Your negative query is embedded and its similarity is <em>subtracted</em> from each track's score. Tracks matching the negative prompt are pushed down in the rankings.</p> | |
| <h4>Weight</h4> | |
| <p>Controls how strongly the negative prompt affects scoring (0.1 = subtle, 1.0 = strong). Default 0.7 works well for most cases.</p> | |
| <h4>Examples</h4> | |
| <ul> | |
| <li>Search "piano music", negative "vocals singing" → instrumental piano</li> | |
| <li>Search "electronic dance", negative "slow ambient" → upbeat electronic only</li> | |
| </ul> | |
| ` | |
| }, | |
| vocals: { | |
| title: 'Vocal Filter', | |
| body: ` | |
| <p>Filter tracks by whether they contain vocals or are instrumental:</p> | |
| <ul> | |
| <li><strong>All:</strong> No filtering, show everything</li> | |
| <li><strong>Instrumental:</strong> Only tracks with no detected vocals (no lyrics and no ASR transcription detected)</li> | |
| <li><strong>With Vocals:</strong> Only tracks where vocals/singing were detected by the ASR model</li> | |
| </ul> | |
| <p>Detection is based on the Parakeet ASR transcription: if a transcription of 10+ characters was generated, the track is considered vocal.</p> | |
| ` | |
| }, | |
| duration: { | |
| title: 'Minimum Duration', | |
| body: ` | |
| <p>Filter out tracks shorter than this duration (in seconds). Default is 60 seconds.</p> | |
| <p>Many AI music platforms generate short clips (15-30 seconds). Setting a minimum duration helps find full-length tracks.</p> | |
| <ul> | |
| <li><strong>0:</strong> Show all tracks regardless of length</li> | |
| <li><strong>60:</strong> At least 1 minute (filters out short clips)</li> | |
| <li><strong>120:</strong> At least 2 minutes (full songs)</li> | |
| </ul> | |
| ` | |
| }, | |
| aesthetics: { | |
| title: 'Minimum Aesthetics Score', | |
| body: ` | |
| <p>Filter tracks by their aesthetics quality score (0-5 scale). The score is a composite of five dimensions computed by the Music-Whisper model:</p> | |
| <ul> | |
| <li><strong>Coherence:</strong> How well-structured and consistent the track is</li> | |
| <li><strong>Musicality:</strong> Musical quality and composition</li> | |
| <li><strong>Memorability:</strong> How catchy or distinctive</li> | |
| <li><strong>Clarity:</strong> Audio clarity and production quality</li> | |
| <li><strong>Naturalness:</strong> How natural/organic it sounds</li> | |
| </ul> | |
| <p>The average across all tracks is ~3.26. Setting the slider to 3.5+ will show only higher-quality tracks. Most tracks score between 2.0 and 4.5.</p> | |
| ` | |
| }, | |
| subset: { | |
| title: 'Source Platform (Subset)', | |
| body: ` | |
| <p>Filter by which AI music platform generated the track:</p> | |
| <ul> | |
| <li><strong>Instrumental Subset</strong> (~11K tracks): Curated collection of instrumental-only tracks with dedicated search indices. Vocal and Asian-tagged content filtered out. Uses separate optimized FAISS/BM25 indices for faster search.</li> | |
| <li><strong>Suno</strong> (308K tracks): Popular AI music generator with diverse styles</li> | |
| <li><strong>Udio</strong> (115K tracks): Known for high-quality generations with good vocals</li> | |
| <li><strong>Mureka</strong> (383K tracks): Largest subset, includes genre/mood metadata</li> | |
| <li><strong>Riffusion</strong> (99K tracks): Spectogram-based music generation. <em>Note: Riffusion audio links went dead during the creation of this dataset, so audio playback will not work for these tracks.</em></li> | |
| <li><strong>Sonauto</strong> (3K tracks): Smallest subset</li> | |
| </ul> | |
| <p><strong>All except Riffusion</strong> is the recommended default since Riffusion audio files are no longer accessible.</p> | |
| ` | |
| }, | |
| safety: { | |
| title: 'NSFW Safety Filter', | |
| body: ` | |
| <p>Filter tracks by their NSFW (Not Safe For Work) safety classification:</p> | |
| <ul> | |
| <li><strong>All:</strong> Show everything, including potentially offensive content</li> | |
| <li><strong>SFW Only:</strong> Exclude tracks flagged as likely NSFW (recommended)</li> | |
| <li><strong>NSFW Only:</strong> Show only flagged content (for research/analysis)</li> | |
| </ul> | |
| <h4>How classification works</h4> | |
| <p>Each track's transcription is compared against reference prompts for three categories: gore/violence, sexual content, and hate speech. Cosine similarity scores above calibrated thresholds trigger NSFW flags.</p> | |
| <p>About 1.4% of tracks (12,860) are flagged as NSFW. The classification is conservative: "very likely" + "likely" labels are both filtered in SFW mode.</p> | |
| ` | |
| }, | |
| languages: { | |
| title: 'Language Filter', | |
| body: ` | |
| <p>Filter tracks by the detected language of their vocal content. Language is detected from the ASR transcription using the <code>langdetect</code> library.</p> | |
| <ul> | |
| <li><strong>All:</strong> No language filtering</li> | |
| <li>Click individual language chips to select one or more languages</li> | |
| <li>Instrumental tracks show as "Unknown" language</li> | |
| </ul> | |
| <p>The most common languages are English (~70% of vocal tracks), followed by Spanish, French, German, and Japanese.</p> | |
