0%The era of basic stem separation is over. While most tools stop at 4 or 6 stems, AudioPod's new Advanced Stem Separation technology goes deeper — much deeper. Using hierarchical AI decomposition, you can now extract up to 16 unique stems from a single job. That 16 is the ceiling on one run — not the size of the catalog, which spans dozens of separable instruments you can pick from. And if you'd rather keep the whole mix minus one part, exclusion mode lets you subtract a single instrument (say, the vocals for a clean instrumental) and leave everything else untouched.
This isn't just incremental improvement. It's a complete reimagining of what stem separation can do for music producers, remixers, DJs, and audio engineers.
Key Takeaways

- Complete breakdown of all 16+ extractable stems
- Pro tips for getting maximum quality from each mode
- Real-world use cases for each separation level
The Problem with Basic Stem Separation
Traditional stem splitters give you the basics:
- 4-stem: Vocals, Drums, Bass, Other
- 6-stem: Vocals, Drums, Bass, Piano, Guitar, Other
That's helpful for simple tasks, but what if you need:
- Just the kick drum for your remix?
- The sub-bass frequencies separated from the mid-bass?
- Center-panned vocals isolated from stereo harmonies and reverb?
- Sustained guitar tones separated from percussive strumming?
Basic stem separation lumps everything together. A "drums" stem includes kick, snare, hi-hat, toms, and cymbals all mixed together. That's not enough control for serious production work.
How Advanced Stem Separation Works
AudioPod's Advanced Stem Separation works in multiple stages to give you maximum detail:
Initial Separation
First, we use cutting-edge AI to extract the 6 main stems: Vocals, Drums, Bass, Piano, Guitar, and Other instruments.
Deep Decomposition
Then we go deeper — breaking drums into individual kit pieces, splitting bass frequencies, separating vocal stereo fields, and dividing guitar sounds.
Quality Check
Every stem passes through quality validation. You only get stems with real, usable audio — never empty or noisy files.
Smart Fallback
If certain elements aren't in the song (like no toms in the drum pattern), we skip them rather than giving you garbage.
The Three Advanced Modes
Producer Mode
8 stems — Perfect for remixing. Get individual drum pieces (Kick, Snare, Hi-Hat) plus all main instruments.
Studio Mode
12 stems — Professional-grade control. Adds Sub-Bass/Mid-Bass split and Center/Stereo vocal separation.
Mastering Mode
16 stems — Maximum detail. Everything in Studio plus Cymbals, Toms, and Guitar Sustain/Strumming separation.
Complete Stem Breakdown
Primary Stems (All Modes)
| Stem | Description | Quality |
|---|---|---|
| Vocals | Complete vocal track | High |
| Drums | Full drum kit | High |
| Bass | Bass instruments | High |
| Piano | Piano and keys | Medium-High |
| Guitar | Guitar tracks | High |
| Other | Remaining instruments | Medium |
Drum Kit Separation (Producer+)
| Stem | What It Contains | Available In |
|---|---|---|
| Kick | The bass drum thump | All Advanced modes |
| Snare | Snare drum hits and rimshots | All Advanced modes |
| Hi-Hat | Hi-hat patterns (open and closed) | All Advanced modes |
| Cymbals | Crash and ride cymbals | Mastering only |
| Toms | Tom fills and rolls | Mastering only |
Kick, Snare, and Hi-Hat are available in all Advanced modes. Cymbals and Toms require Mastering mode and are only extracted when they're actually present in the song.
Vocal Stereo Analysis (Studio+)
| Stem | Description | Use Case |
|---|---|---|
| Center Vocals | The main lead vocal in the middle of the mix | Isolate the primary singer, remove effects |
| Stereo Vocals | Harmonies, backing vocals, and reverb in the sides | Extract backing vocals, doubles, and spatial effects |
This separates what's in the "center" of your speakers (usually the lead vocal) from what's spread across the "sides" (harmonies, reverb, and backing vocals). It's the same technique professional mastering engineers use.
Bass Frequency Split (Studio+)
| Stem | What It Contains | Use Case |
|---|---|---|
| Sub-Bass | The deep rumble you feel more than hear | Perfect for club systems and adding punch |
| Mid-Bass | The melodic bass notes and groove | Great for mixing and balancing with other instruments |
The split uses professional-grade audio processing to separate the deep sub frequencies from the melodic bass content. Both stems combine perfectly back to the original with no audio artifacts.
Guitar Separation (Mastering Only)
| Stem | What It Contains | Use Case |
|---|---|---|
| Guitar (Sustain) | Ringing chords, melodies, sustained notes | Ambient textures, pad-like elements |
| Guitar (Strumming) | Pick attacks, rhythmic strumming, percussive hits | Rhythmic grooves, adding energy |
This separates the "ringing" sustained guitar sounds from the "attack" sounds like strumming and picking. Perfect for isolating either the melodic or rhythmic elements of guitar parts.
Additional Instruments
| Stem | What It Contains | Available In |
|---|---|---|
| Synth | Synthesizers, electronic sounds, pads | All Advanced modes |
| Percussion | Shakers, tambourines, congas, and other hand percussion | Studio & Mastering |
What You'll Get from Each Mode
Producer Mode (8 Stems)
- Vocals
- Kick, Snare, Hi-Hat (individual drum pieces)
- Bass, Guitar, Piano
- Other Instruments
Studio Mode (12 Stems)
- Vocals + Center Vocals + Stereo Vocals
- Kick, Snare, Hi-Hat
- Sub-Bass + Mid-Bass
- Guitar, Piano, Synth, Percussion
Mastering Mode (16 Stems)
- Vocals + Center Vocals + Stereo Vocals
- Kick, Snare, Hi-Hat, Cymbals, Toms
- Sub-Bass + Mid-Bass
- Guitar (Sustain) + Guitar (Strumming)
- Piano, Other, Synth, Percussion
Note: The actual stem count depends on what's present in the audio. If a song has no toms, you won't get a toms stem — but you'll never get a silent/empty file either.
How to Get Maximum Quality
1. Start with High-Quality Source
Best Sources
- Lossless formats (WAV, FLAC) - 44.1kHz or higher sample rate - 16-bit or 24-bit depth - Official releases/masters
Avoid If Possible
- Low bitrate MP3 (under 192kbps) - YouTube rips (compressed) - Live recordings with bleed - Heavily limited/clipped masters
2. Choose the Right Mode
| What You Want to Do | Best Mode |
|---|---|
| Quick karaoke or instrumental version | Basic 2-stem |
| Remix with separate drum pieces | Producer (8 stems) |
| Professional mix work with full control | Studio (12 stems) |
| Maximum detail and every possible element | Mastering (16 stems) |
3. Results Depend on the Song
Not every song will produce every stem — and that's by design:
- No piano in the song? You won't get a piano stem
- No tom fills in the drums? Toms won't appear
- Mono recording? Stereo Vocals will be minimal
We only give you stems with actual content. No empty files, no garbage.
How It Works (Behind the Scenes)
Drum Kit Separation
Our AI listens to the drums and identifies each hit:
- Finds the beats: Detects exactly when each drum is hit
- Analyzes the sound: Determines if it's a kick, snare, hi-hat, cymbal, or tom
- Separates cleanly: Rebuilds each drum element as its own track
- Quality check: Only includes stems that have real content
Bass Splitting
The bass is split at 80Hz — the sweet spot between "feel" and "hear":
- Sub-Bass: Everything below 80Hz (the rumble you feel in your chest)
- Mid-Bass: Everything above 80Hz (the notes you can hum along to)
Both parts combine back to the original perfectly — no audio weirdness.
Vocal Stereo Analysis
We separate what's in the center vs. the sides of the stereo field:
- Center: The main vocal that's front and center
- Sides: Everything spread across the stereo field (harmonies, reverb, doubles)
This is the same technique professional mastering engineers use.
Guitar Separation
Guitars have two distinct sounds — the sustained ring and the percussive attack:
- Sustain: The ringing, melodic, chord-like sounds
- Strumming: The rhythmic, percussive attack sounds
We separate these so you can use either independently.

Frequently Asked Questions
Why don't I always get 16 stems in Mastering mode?
The number of stems depends on what's actually in the song. If a track has no piano, toms, or certain instruments, those stems won't appear. We only give you stems with real, usable audio — never empty or garbage-filled files.
Can I use these stems commercially?
That depends on whether you have rights to the original song. If you own the music or have proper licenses, go for it. Always respect copyright when using extracted stems. Learn more about legal sampling with stems.
How is this different from other stem splitters?
Most tools stop at basic separation (vocals, drums, bass). We go much deeper — breaking drums into Kick, Snare, Hi-Hat, Cymbals, and Toms. Splitting bass into Sub-Bass and Mid-Bass. Separating vocals into Center and Stereo. And dividing guitars into Sustain and Strumming sounds.
