AudioCraft Integration: AI Music and Sound Generation for Your Project

Problem: how to create 100 unique sounds for a mobile RPG in a week without a huge budget?

Hiring a sound designer is expensive, and buying ready-made libraries quickly drains resources. The solution is to deploy AudioCraft from Meta directly in your infrastructure. The framework combines MusicGen for music, AudioGen for effects, and EnCodec for compression down to 24 kbps. We help integrate this stack into your project—from web services to game engines. Contact us for a consultation on your project.

What problems does AudioCraft solve?

Generating unique audio content without royalty fees. MusicGen creates music from text descriptions—from epic orchestral pieces to minimalist ambient. AudioGen generates sound effects: footsteps, doors, gunshots, nature noises. EnCodec provides lossy compression for streaming. AudioCraft reduces audio costs by a factor of 10 compared to buying ready-made libraries. For example, a single sound license can be very expensive, but with AudioCraft all sounds are free (MIT license). Moreover, AudioCraft requires 3 times less GPU memory than similar models, making it accessible even on a single GPU.

How we configure generation for your project

We select models and hyperparameters for specific scenarios. For an open-world RPG, you need 50+ background tracks of 3–5 minutes—MusicGen generates a track in seconds. For a casual game, AudioGen with simple effects suffices. If customization is needed, we use fine-tuning with LoRA—the model is fine-tuned on your audio files in just 2–3 hours on a single GPU. LoRA (Low-Rank Adaptation) allows fine-tuning on 10–20 files without retraining the entire network, reducing GPU costs by 80% and accelerating iterations. We apply LoRA to both EnCodec and MusicGen to adapt to specific instruments or styles.

Stack: PyTorch, Hugging Face Transformers, TorchAudio. Deployment via Triton Inference Server or ONNX Runtime for latency as low as 50 ms.

# Example MusicGen integration
from audiocraft.models import MusicGen
model = MusicGen.get_pretrained("facebook/musicgen-medium")
model.set_generation_params(duration=8, temperature=0.9)
wav = model.generate(["upbeat electronic track with synth bass"])

We provide a ready-made REST API for AudioGen and MusicGen, wrapped in FastAPI with OpenAPI documentation.

Why AudioCraft is better than ready-made libraries

AudioCraft gives you full control: you can fine-tune the model on your audio files with LoRA, apply quantization (INT8) for CPU inference acceleration, and deploy in an isolated network.

Real-world case: generating sounds for a mobile game

A client wanted to sound an RPG: about 100 sound effects (footsteps on different surfaces, spells, monsters). Hiring a sound designer would have cost a significant amount—they saved that budget by choosing AudioCraft. We used AudioGen with the SFX_LIBRARY and generated all sounds in 2 days. Result: 98% of sounds accepted without revisions. EnCodec compressed them to 48 kbps—the package size decreased by a factor of 4.

Integration process

1. Analysis: define use cases, target audio duration, generation frequency.
2. Design: choose models (MusicGen/AudioGen), pipeline architecture (batch/streaming), output format (WAV, MP3, OGG).
3. Implementation: write integration code in Python, wrap in REST API (FastAPI) or gRPC service.
4. Testing: measure quality (MOS, MUSHRA), latency (p99), throughput (generations/sec).
5. Deployment: set up CI/CD, monitoring (Prometheus), auto-scaling on Kubernetes.

What is included in the work

• Ready-made audio generation module supporting MusicGen, AudioGen, and EnCodec.
• REST API with OpenAPI documentation.
• Integration with your engine (Unity, Unreal Engine, Web).

Generative AI Development: From Prompt to Production API

We often receive a task "generate a product image" — on the surface it seems simple. But behind this lies a choice between dozens of models, configuring the inference pipeline, manually solving consistency issues, integrating into the product backend, and answering why the model generates hands with six fingers in staging but not in production. Let's break down the directions we work with.

Image Generation: From Prompt to Production API

The current landscape includes FLUX.1 [dev/schnell/pro] from Black Forest Labs and Stable Diffusion 3.5. FLUX.1 [schnell] takes 4 steps instead of 20–50 for SDXL — 5–12 times faster — while maintaining higher quality. On an A100 80GB — 1.2–1.8 s per 1024×1024 image at batch_size=4.

A typical deployment issue: FLUX.1 [dev] requires 24+ GB VRAM in fp16. On A10G 24GB it fits tightly; at batch_size>1 — OOM. Solution: torch_dtype=torch.bfloat16 + enable_model_cpu_offload() from diffusers, or quantization via bitsandbytes to NF4 — minimal quality drop, memory consumption drops to 12–14 GB.

ControlNet and IP-Adapter are key tools for production tasks where controllability is needed. ControlNet with Canny/Depth/Pose maps provides structural control. IP-Adapter (especially IP-Adapter-FaceID) allows transferring character identity to generations — this is the foundation for personalized content. More about ControlNet can be found on Wikipedia.

Case study: e-commerce photography. A retailer with 8000 SKUs needed lifestyle photos for each product. Pipeline: product segmentation (Segment Anything Model 2) → background removal → inpainting with FLUX.1 [dev] using product image as IP-Adapter reference → upscale via RealESRGAN_x4plus. The generation cost is negligible compared to professional photography, providing huge savings. Throughput — 200 images/hour on 2× A100. Our extensive experience from 30+ projects ensures we select the optimal model for your task — an evaluation can be obtained upfront.

Why Is Model Selection Only Half the Battle?

Fine-tuning for a Specific Style or Character

Dreambooth and LoRA are the standard for adapting to a specific visual style or object. LoRA trains in 2–4 hours on 20–30 reference images on a single A100. Rank 16–32 is usually sufficient for style; rank 64+ is needed for precise face reproduction.

A common mistake: training LoRA too long — the model overfits to references, losing the ability to vary. Sign: at cfg_scale=7, all images look like copy-paste of references. Solved by early stopping (usually 1500–2000 steps for 20 images) and prior_preservation_loss.

For deeper customization — full fine-tuning via diffusers + accelerate with FSDP on multiple GPUs. But that already takes 40–80 hours of training and requires a truly large dataset (1000+ images).

Comparison of Image Generation Approaches

Video Generation: Which Models Are Best?

Open-weight video models still lag behind commercial ones in stability and length. Wan2.1 is the best choice for self-hosting: 14B parameters, runs on 2× A100, delivers acceptable quality for short clips.

The main pain of video generation is temporal consistency: the character changes clothing color at the third second, objects "drift." Partial solution — generation with motion_bucket_id and noise_aug_strength in Stable Video Diffusion, or using I2V (image-to-video) instead of pure text-to-video. As noted in VideoPoet research, consistency is achieved by training on long sequences.

AnimateDiff remains a working tool for short loops and motion effects on top of SD/FLUX. Not Sora, but deployable locally and predictable.

Music and Audio Generation

AudioCraft from Meta (MusicGen + AudioGen) is a production-ready stack for music generation. musicgen-large (3.3B) generates 30 s of music in ~8 s on A100. Control via text prompt and melody conditioning — you can specify a melody by humming.

Stable Audio Open from Stability AI is an alternative with length up to 47 s, better structural control (intro/verse/chorus). Deployment is similar: diffusers + FastAPI.

For voice-over and dubbing — ElevenLabs API or self-hosted XTTS v2 (see Speech AI service). For sound design and foley — AudioGen.

3D Generation: Current Practical State

3D generation has not yet reached the same maturity as 2D. But for specific tasks, tools are already working:

TripoSG and Shap-E — text/image-to-3D. Shap-E from OpenAI generates simple 3D meshes in seconds, but geometry is rough. TripoSG gives more detailed results but requires post-processing (remeshing, UV unwrapping).

Wonder3D and Zero123++ — 3D reconstruction from a single image. They work by generating multi-views (6–8 views) and then 3D reconstruction via NeuS or instant-ngp.

Gaussian Splatting (3DGS) — not generation, but reconstruction from a series of photos/videos. For product cards and real estate it's already production: 50–200 photos → 3DGS model in 15–30 min on RTX 4090 → interactive 3D viewer in browser.

What Infrastructure Is Needed for Generative AI Deployment?

Critical for generative models:

• Task queue — Celery + Redis or Ray Serve. Synchronous HTTP for image generation is unacceptable with >5 concurrent requests.
• Caching — similar prompts yield similar results. Semantic cache via embeddings (faiss + sentence-transformers) can reduce GPU load by 20–40%.
• Quality monitoring — CLIP score for text-image alignment, FID for evaluating generation distribution. Integrate into MLflow or Weights & Biases.
• Storage — generated images immediately to S3/MinIO, not on the inference server disk.

What's Included in the Deliverables

We take the project turnkey — from model selection to deployment and monitoring. The result includes:

• Model (or API integration) with performance benchmarks (latency p99, throughput).
• Pipeline documentation (prompt engineering guide, model card, dependency versions).
• Integration with your backend (REST/gRPC, queues).
• Configured monitoring (dashboards, alerts for quality drift).
• Training workshop for the team (2–4 hours).
• Warranty support for 3 months after launch — as part of our quality certificate.

We have completed 30+ projects in generative AI — this gives us the right to guarantee results.

How Is the Generative AI Development Process Structured?

1. Analysis (1–2 days): audit of current architecture, clarification of use case, selection of models and success metrics. We evaluate the project free of charge.
2. Proof of Concept (1–3 weeks): quick prototype on your data — to see real quality, not blog demos.
3. Design (1–2 weeks): pipeline architecture, infrastructure (GPU cluster/API), A/B testing plan.
4. Implementation and fine-tuning (4–12 weeks): development, LoRA/full fine-tuning, integration with queue and cache.
5. Testing (1–2 weeks): load tests, metric validation, edge-case verification (negative scenarios).
6. Deployment and monitoring (1–2 weeks): production deployment, monitoring setup, documentation.

Timeline Estimates

Integration of a ready API (DALL·E 3, Midjourney API, Stability API) — 1–2 weeks. Self-hosted pipeline with fine-tuning — 6–12 weeks. Full platform with UI, queues and monitoring — 3–6 months. The specific cost is calculated individually after analyzing your scenario.
