 # Features
 
-- expression parsing with support for functions and variables:
-  - functions:
-    - run expressions on both components of CONDITIONING (not that I know what they do), LATENT, IMAGE, NOISE and FLOAT
-    - math operators (binary and unary +,- and ^,*,/,%)
-    - boolean operators (false = 0.0; true = 1.0) (<,<=,>,>=,==,!=)
-    - sin, cos, tan
-    - asin, acos, atan (can produce NaN outside range -1...1)
-    - atan2 (x,y)
-    - sinh, cosh, tanh 
-    - asinh, acosh, atanh (can produce NaN outside range -1...1)
-    - abs, sqrt (produces NaN on negative numbers), ln (log with base e), log (base 10), exp, pow
-    - smin, tmin, smax, tmax, tnorm, snorm (norm and t prefixed are not applicable on float math node)
-      - s prefixed return one number
-      - t prefixed work element-wise
-    - floor, ceil, round, gamma, clamp, sigm (sigmoid)
-    - angle (audio node)
-  - variables
-    - a, b, c, d : inputs of type based on node
-    - w, x, y, z : each node allows use of 4 additional floats
-    - W : Width of tensor - does not work on FLOAT and CONDITIONING
-    - H : Height of tensor - does not work on FLOAT and CONDITIONING
-    - C : Channel of tensor - used as color chanel in IMAGE or as information channel in others. does not work on FLOAT and CONDITIONING
-    - B : Batch - does not work on FLOAT and CONDITIONING
-    - X : X position in tensor - does not work on FLOAT and CONDITIONING
-    - Y : Y position in tensor - does not work on FLOAT and CONDITIONING
-    - I : Tensor used to initalise sampler before noise injection - usually zeroed out and generated by Empty Latent Image node - Exclusive for NOISE
-  - use constant e and pi
+- functions and variables in math expressions
+- Nodes for CONDITIONING, LATENT, IMAGE, NOISE, FLOAT, and AUDIO
+
+## Operators
+- Math: `+`, `-`, `*`, `/`, `%`, `^`
+- Boolean: `<`, `<=`, `>`, `>=`, `==`, `!=`  
+  (`false = 0.0`, `true = 1.0`)
+
+## Functions
+- Basic: `abs`, `sqrt`, `ln`, `log`, `exp`, `pow`
+- Trigonometric: `sin`, `cos`, `tan`, `asin`, `acos`, `atan`, `atan2`
+- Hyperbolic: `sinh`, `cosh`, `tanh`, `asinh`, `acosh`, `atanh`
+- Aggregates: `smin`, `smax` , `snorm` (scalar), `tmin`, `tmax`, `tnorm` (elementwise)
+- Other: `floor`, `ceil`, `round`, `gamma`, `clamp`, `sigm` (sigmoid), `angle` (in ifft only)
+- Audio-specific: `fft` (short-time FFT), `ifft` (inverse sFFT **always return audio back to time domain before leaving node**)
+
+## Variables
+- **Inputs**: `a`, `b`, `c`, `d` (matches node input type)  
+- **Extra floats**: `w`, `x`, `y`, `z`   
+- **Tensor positions**:  `C` (channel), `B` (batch), `X`, `Y`, `W` (width), `H` (height) (not for FLOAT/AUDIO/CONDITIONING)
+- **Special**:
+  - `I` – sampler init tensor (for NOISE only)  
+  - `S` – current audio sample (AUDIO only)  
+  - `T` – audio length  (AUDIO only)  
+  - `R` – sample rate (AUDIO only)  
+  - `F` – frequency count (freq domain, iFFT only)  
+  - `K` – current frequency (freq domain, iFFT only)  
+- Constants: `e`, `pi`
