IMPLEMENTASI TEKNIK MIXING LOW-PASS, HIGH-PASS, DAN ALL-PASS FILTER PADA PROSES AUDIO GENERAL DEMPO PAGAR ALAM

Abstrak

Penelitian ini bertujuan untuk menentukan teknik mixing yang paling efektif di antara low-pass, high-pass, dan all-pass filter dalam proses audio untuk video General Dempo Pagar Alam. Perbandingan dilakukan menggunakan metode Spectrum Analyzer untuk menganalisis spektrum frekuensi dan mengevaluasi kualitas audio. High-pass filter terbukti efektif menghilangkan frekuensi rendah di bawah 100 Hz, sedangkan low-pass filter mengurangi frekuensi tinggi di atas 1 kHz. Sementara itu, all-pass filter tidak mempengaruhi amplitudo frekuensi, melainkan hanya mengubah fase sinyal. Hasil analisis menunjukkan bahwa pemilihan filter harus disesuaikan dengan kebutuhan spesifik setiap track audio. High-pass filter cocok untuk menghilangkan noise rendah, low-pass filter efektif dalam meredam frekuensi tinggi yang tajam, dan all-pass filter berguna untuk manipulasi fase tanpa mengubah karakteristik frekuensi asli. Kesimpulan penelitian ini menegaskan pentingnya penggunaan filter yang tepat guna meningkatkan kualitas audio secara keseluruhan.

This research aims to determine the most effective mixing technique among low-pass, high-pass, and all-pass filters in the audio processing for the General Dempo Pagar Alam video. The comparison was conducted using the Spectrum Analyzer method to analyze the frequency spectrum and evaluate audio quality. The high-pass filter proved effective in eliminating low frequencies below 100 Hz, while the low-pass filter reduced high frequencies above 1 kHz. Meanwhile, the all-pass filter does not affect frequency amplitude but only alters the signal phase. The analysis results indicate that filter selection should be tailored to the specific needs of each audio track. High-pass filters are suitable for removing low-frequency noise, low-pass filters are effective in attenuating sharp high frequencies, and all-pass filters are useful for phase manipulation without altering the original frequency characteristics. The conclusion of this study emphasizes the importance of using the appropriate filter to enhance overall audio quality.
