Abstract
Keamanan adalah hal yang penting dalam komunikasi digital. Steganografi pada suara digital adalah teknik untuk menyembunyikan informasi rahasia kedalam suara digital. Penelitian ini bertujuan menemukan nilai amplitudo yang tepat metode echo hiding yang dapat menghasilkan nilai ketersembunyian (signal noise to ratio) dan pemulihan pesan (recovery rate) yang paling optimal pada masing-masing genre musik digital. Untuk menyembunyikan pesan dengan kesuksesan pemulihan 100% dan ketersembunyian yang optimal, penggunaan parameter amplitudo harus diatur sedemikian rupa. Berdasarkan hasil pengujian, ampltudo dengan nilai 0.9 memberikan hasil terbaik pada genre musik jazz, pop, dan rock dengan masing-masing nilai recovery rate sebesar 68.75%, 95%, dan 87.5% serta nilai SNR ( signal noise to ratio) masing-masing sebesar 2.086dB, 2.71dB, dan 2.372db. Musik dengan genre metal menunjukan hasil optimal pada amplitudo 0.6 dengan recovery rate sebesar 100% dan SNR 5.444db.
