Who should use the Separate audio stems workflow workflow?
Teams or solo builders working on creativity tasks who want a repeatable process instead of one-off tool experiments.
AI Workflow · Creativity
A streamlined workflow to isolate individual audio stems (vocals, drums, bass, etc.) from a mixed track using AI separation, then normalize loudness for consistent output.
Deliverable outcome
Finalized, export-ready stems with consistent naming and format.

Step map
Instead of relying on a single generic AI model, this pipeline connects specialized tools to maximize quality. First, you'll use Audacity (Noise Reduction & AI Suppression) to a clean, standardized input file ready for ai separation. Then, you pass the output to LALAL.AI to isolated stems for vocals, drums, bass, and other instruments, saved as individual files. Then, you pass the output to Auphonic to all stems have consistent loudness levels, ready for mixing or further processing. Then, you pass the output to iZotope RX to clean, artifact-free stems suitable for professional use. Finally, Audacity (Noise Reduction & AI Suppression) is used to finalized, export-ready stems with consistent naming and format.
Prepare the mixed audio file
A clean, standardized input file ready for AI separation.
Separate audio stems using AI
Isolated stems for vocals, drums, bass, and other instruments, saved as individual files.
Normalize loudness of each stem
All stems have consistent loudness levels, ready for mixing or further processing.
Review and adjust stem quality
Clean, artifact-free stems suitable for professional use.
Export stems in desired format
Finalized, export-ready stems with consistent naming and format.
Ensure the input file is a high-quality, stereo mixed track (e.g., WAV or FLAC) with no clipping or heavy compression that could confuse the AI. Trim silence at the beginning and end to avoid processing artifacts.
Why Audacity (Noise Reduction & AI Suppression): Audacity is a free, widely-used audio editor that can prepare mixed audio files, including trimming, format conversion, and basic cleanup.
Upload the prepared file to a stem separation tool (e.g., Spleeter, Demucs, or a cloud service like Lalal.ai) and select the desired stem types (vocals, drums, bass, other). Process the file to generate individual audio tracks.
Why LALAL.AI: LALAL.AI is a dedicated AI stem separation tool that accurately isolates vocals and instruments from mixed audio.
Apply loudness normalization to each stem to achieve a consistent integrated loudness (e.g., -14 LUFS for streaming compatibility) using a tool like ffmpeg-normalize or a DAW loudness meter. This ensures no stem is too quiet or too loud relative to others.
Why Auphonic: Auphonic is a professional tool for loudness normalization (LUFS) and intelligent leveling, ideal for ensuring consistent stem loudness.
Listen to each normalized stem for artifacts (e.g., bleeding, phasing, or distortion) from the AI separation. Use a spectral editor or EQ to clean up any unwanted noise or cross-talk between stems.
Why iZotope RX: iZotope RX is a spectral editor specifically designed for audio repair, allowing detailed review and adjustment of stem quality.
Export each stem as a high-quality audio file (WAV or FLAC) with consistent naming (e.g., 'SongTitle_Vocals.wav'). Optionally, create a stereo mix of all stems to verify alignment and phase coherence.
Why Audacity (Noise Reduction & AI Suppression): Audacity can export audio in multiple formats (WAV, MP3, FLAC, etc.), making it a reliable tool for final stem export.
§ Before you start
Teams or solo builders working on creativity tasks who want a repeatable process instead of one-off tool experiments.
No. Start with the top pick for each step, then replace tools only if they do not fit your pricing, compliance, or output needs.
Open the mapped task page and compare top options side by side. Prioritize output quality, integration fit, and predictable cost before scaling.
