Professional studios spend thousands on acoustic treatment, but for the rest of us, <strong>Digital Signal Processing (DSP)</strong> offers a software-based solution. By applying precise digital filters to your audio signal, you can correct for room modes, speaker non-linearities, and crossover issues — all from a $35 Raspberry Pi.</p> https://www.pistack.xyz/posts/2026-06-07-self-hosted-signal-processing-sdr-gnuradio-liquid-dsp-soapysdr/ Sun, 07 Jun 2026 00:00:00 +0000 https://www.pistack.xyz/posts/2026-06-07-self-hosted-signal-processing-sdr-gnuradio-liquid-dsp-soapysdr/ <h2 id="introduction">Introduction</h2> <p>Software-Defined Radio (SDR) has revolutionized RF engineering by moving signal processing from specialized hardware into software. Whether you&rsquo;re decoding satellite telemetry, analyzing cellular signals, building a DIY radar, or just listening to amateur radio bands, the core of every SDR application is the <strong>signal processing pipeline</strong> — the chain of filters, demodulators, decoders, and synchronizers that turn raw IQ samples into meaningful data.</p>
