Pydub yordamida Pythonda wav fayllari bilan ishlash
Audio fayllar axborot uzatishning keng tarqalgan vositasidir. Keling, Python yordamida audio fayllar bilan qanday ishlashni ko'rib chiqamiz. Python audio fayllar bilan ishlash uchun pyydub deb nomlangan modulni taqdim etadi . pydub faqat .wav fayllari bilan ishlash uchun Python kutubxonasidir . Ushbu kutubxonadan foydalanib, biz . wav audio fayllar.

O'rnatish

pip install pyydub
Quyida pydub tomonidan bajarilishi mumkin bo'lgan ba'zi funktsiyalar mavjud:

1. 
   Audio fayl ijro etilmoqda.
   
2. 
   Biz uzunlikdagi kanallar kabi fayl haqida ma'lum ma'lumotlarni olishimiz mumkin.
   
3. 
   Berilgan .wav faylining hajmini oshirish/kamaytirish.
   
4. 
   Ikki yoki undan ortiq audio fayllarni birlashtirish.
   
5. 
   Audio fayl eksport qilinmoqda.
   
6. 
   Audio faylni bo'lish.
   

1. 
   Audio faylni tinglash: Bu play() usuli yordamida amalga oshiriladi 
   
2. 
   2) .wav fayli haqida bilish: buning uchun audio fayl ob'ektining atributlaridan foydalanamiz .

39. 
    print(wav_file_new.frame_rate)
    

3) Fayl hajmini oshirish/kamaytirish: ' +' va ' -' operatorlari yordamida.

4) Fayllarni birlashtirish: Bu '+' operatori yordamida amalga oshiriladi .


5) Fayllarni eksport qilish: Bu eksport() usuli yordamida amalga oshiriladi .

6) Ovozni ajratish: split_to_mono() usuli yordamida audioni ajratish .
