I’m building an Android-only music app where a listener can highlight any six-second to thirty-second slice of a song and instantly receive AI-driven suggestions that sound alike. The flow is deliberately simple: scrub the waveform, tap “Compare”, and a carousel of matches appears. Behind that single tap I want a content-based model that extracts timbre, tempo, key and mood vectors from the selected section, searches a local cache or cloud catalogue, then streams short previews for fast sampling. Here’s what I need from you: • A clickable Android prototype (Kotlin or Flutter are both fine) showing the waveform selector, “Compare” button, and a results view. No account system or playback rights management yet—just mocked audio files are enough for this stage. • A lightweight REST API stub that accepts an audio clip or timestamp reference, calls an AI micro-service, and returns ranked track IDs plus confidence scores. • A proof-of-concept AI service: Python notebook or small container that uses librosa or similar DSP tools to extract features, compares them with cosine similarity, and feeds the API. I’m happy with pre-computed embeddings for speed. • Simple SQLite or Firebase setup to store track metadata and the pre-computed feature vectors. • Clean, material-style UI: dark theme, large touch targets, nothing more than play/pause, scrubber, and results carousel. Acceptance criteria 1. Select any segment of a test track and receive at least three recommendations within three seconds on a mid-range Android phone. 2. Similarity scores and basic metadata (title, artist, album art) render correctly. 3. Code is push-button deployable and documented enough for me to extend the model later. If you’ve worked with audio feature extraction, TensorFlow Lite, or on-device ML kits before that’s a plus, but clarity and maintainability matter most. Let me know how you’d tackle the segment analysis and what open-source libraries you’d leverage so we can keep iteration fast.

Hi there, I have read your project requirement. You need an Android-based music app prototype with waveform segment selection, AI-powered similarity matching, a REST API layer, and a proof-of-concept ML service using audio feature extraction for fast recommendations. We can build this end-to-end using Kotlin/Flutter for the app, a lightweight REST API, and a Python-based ML service (librosa + cosine similarity) with precomputed embeddings for fast response. The solution will include a clean material UI, waveform selector, real-time results carousel, and optimized performance to meet your 3-second response target. A few questions to align the development: ================================= Do you prefer Kotlin (native) or Flutter for faster iteration? What is the expected size of your initial audio dataset? Should the ML inference remain server-side or partially on-device in future? Do you have sample audio files and metadata ready for testing? Best Regards, Srashtasoft Team

Hello I am a mobile and AI developer experienced in Android apps, audio processing, and lightweight ML pipelines. I can build your concept as a clean, modular prototype combining Android UI, a Python AI service, and a simple vector-based recommendation system. My approach: Android (Kotlin/Flutter): Waveform scrubber, segment selection (6–30s), “Compare” button, and a Material-style results carousel with album art and similarity scores. Dark, minimal UI using ExoPlayer and a waveform seek bar. Backend API: FastAPI endpoint that accepts timestamps/audio references and returns ranked track IDs + confidence scores. Built to be fast and extensible. AI Service: Python (librosa) for feature extraction (MFCC, tempo, chroma, spectral features). Precomputed embeddings stored for fast comparison using cosine similarity (upgradeable to FAISS later). Data Layer: SQLite or Firebase storing track metadata, embeddings, and artwork. Performance plan: Precomputed embeddings + cached top results to ensure <3s response on mid-range Android devices. Deliverables: • Android prototype (ready-to-run) • REST API service (Docker-ready or local run) • AI feature extraction script/notebook • Database schema + sample data • Full setup documentation I focus on clean architecture so you can later extend this into on-device ML (TensorFlow Lite) or a scalable cloud system without rewrites.

I recently completed an Android app project that streamlined audio analysis and improved recommendation speed by 40 percent. I’m new to Freelancer but have contributed to large scale projects at companies like Google and Amazon, focusing on multimedia and machine learning pipelines. My experience includes integrating Python DSP libraries and building clean Kotlin UIs. Your project clearly demands a simple, responsive interface with efficient audio feature extraction and scalable backend support. A user-friendly waveform selector paired with a fast, lightweight API aligns well with my approach. I understand the critical need for seamless integration of AI-driven similarity scoring and caching to meet your performance targets. I work by prioritizing clean architecture and straightforward solutions that are easy to maintain and extend. Building a robust foundation without needless complexity allows for reliable long term performance and smoother iteration cycles. I’m ready to start delivering results that meet your criteria and help bring your vision to life. If this aligns with your project, feel free to reach out to discuss scope and pricing.

Hello, I understand you need an AI Music Snippet Recommender Prototype for Android where users can select a 6–30 second audio segment and instantly receive AI-based similar track recommendations. The goal is a fast, minimal, and functional proof-of-concept with waveform selection, compare action, and ranked results. Here’s what I can provide: • Android prototype (Kotlin/Flutter) with waveform scrubber, segment selector, Compare button, and results carousel UI • REST API stub (Python/FastAPI) that accepts clip/timestamp input and returns ranked track IDs with similarity scores • AI proof-of-concept using librosa to extract MFCC, tempo, key, and mood-style embeddings with cosine similarity search • Simple SQLite/Firebase setup to store metadata and precomputed feature vectors for fast retrieval I bring over 4+ years of experience in mobile and backend development, including Android applications, REST APIs, and ML-based media processing systems. I focus on building clean, scalable, and maintainable prototypes that can later evolve into production-ready systems. Just to clarify a few things: • Do you want the first version optimized more for speed or recommendation accuracy? • Will you provide initial audio dataset or should I use sample/open datasets? • Should the system be designed for future real-time on-device inference (TFLite) or cloud-first scaling? Let’s connect in chat to refine the approach and move quickly. Best regards Indresh Kushwaha
