Hardtiming

Hardtiming refers to a condition that can affect certain types of audio hardware, particularly older digital audio converters or samplers. It occurs when a digital audio signal is sampled at a rate that is slightly inconsistent with the intended sample rate of the device. This inconsistency, even if very small, can lead to audible artifacts or inaccuracies in the playback of the audio.

The term "hardtiming" implies a rigid or unyielding adherence to a specific clock signal for sampling. When this clock signal deviates even minutely from the expected frequency, the sampling process becomes "hard" to align correctly. This can manifest as a subtle form of distortion, pitch instability, or a general lack of clarity in the sound. It is not a problem with the audio data itself, but rather with the precision of the hardware's internal clock used for digital-to-analog conversion or signal processing.

Modern audio equipment generally employs highly stable clocking mechanisms, making hardtiming a less common issue. However, it can still be a consideration when working with vintage gear or in specialized audio applications where extreme precision is paramount. Troubleshooting hardtiming often involves ensuring that external clock sources are perfectly synchronized or by using internal clocks known for their stability. The effects of hardtiming are often subtle and may not be noticeable to all listeners, but they can be significant for audiophiles and professionals seeking the highest fidelity.
