ippStsTrnglFreqErr
A triangle wave is still a sampled periodic signal, so its frequency must satisfy the normalized digital-frequency range accepted by the routine.
If the value came from Hz, verify the sample rate and normalization before suspecting output-buffer layout.
Check these details for ippStsTrnglFreqErr
- Hz-to-normalized-frequency conversion.
- Nyquist boundary conditions.
- Frequency changes during streaming.

Interpreting ippStsTrnglFreqErr
ippStsTrnglFreqErr is Intel IPP status -42. AllStat describes it as “Triangle frequency is negative, or greater than, or equal to 0.5.”. For ippStsTrnglFreqErr, the decisive context is the exact IPP routine and overload, because status names are shared across image, signal, codec, cryptography, and data-compression domains with different parameter contracts.
Developer checks for ippStsTrnglFreqErr
- Record the full function name, library version and CPU dispatch, source and destination types, ROI or vector length, step values, scale factor, and every state/specification object passed to the call.
- Validate the ippststrnglfreqerr parameter group before changing buffers: initialization routines often establish constraints inherited by later processing calls.
- For ippStsTrnglFreqErr, use ippGetStatusString for logging but branch on the numeric IppStatus value; localized or wrapper text is not a stable program contract.
Retrying ippStsTrnglFreqErr with unchanged arguments normally reproduces the same validation failure. For ippStsTrnglFreqErr, rebuild the affected IPP state when configuration changed, verify buffer bounds and alignment, and isolate the smallest call that still returns the status.
