Abstract

Proses embedding dalam steganografi audio stereo didefinisikan sebagai penyembunyian informasi dalam host audio stereo yang menghasilkan stego audio. Dalam jurnal ini, LWT-DST pada steganografi audio stereo diproses dengan menggunakan akuisisi Compressive Sampling (CS). Pertama, dilakukan teknik Lifting Wavelet Transform (LWT) pada host audio. Lalu, kita pilih satu sub-band dari hasil proses sebelumnya yang akan dilakukan teknik Discrete Sine Transform (DST) untuk mengubah sinyal dari domain waktu ke domain frekuensi. Sebelum proses penyisipan, akuisisi Compressive Sampling (CS) diaplikasikan pada pesan rahasia. Menurut penggunaan teknik gabungan tersebut diharapkan transparansi bisa menjadi baik dengan SNR > 25, ODG > -1, dan BER 5%.
