Amma was already lost in the wormhole scene. Arnav knew Amma would watch again later. So he paused the movie, tapped the same menu, and selected Set as default audio track (a feature in newer MX Player versions). Now every time she played that file, Hindi would be the first choice. The Real Lesson Later that evening, after the movie ended (Amma cried at the tesseract scene and declared it “better than Krrish ”), Arnav explained to his cousin:
“See, MX Player itself doesn’t download Hindi audio from the internet. But if your video file already has multiple audio tracks—like in Blu-ray rips, official downloads, or some streaming captures—you can switch easily. And for missing audio? You can download a separate Hindi AAC or MP3 file and use the ‘External Audio Track’ option under Audio settings.”
That’s when Arnav remembered: MX Player had a hidden superpower. Arnav knew that for Hindi audio to work, the video file itself needed to have multiple audio tracks embedded—like an MKV file (not a simple MP4). Luckily, he had downloaded Interstellar (2014).mkv from a legal source (he was careful about that). how to download hindi audio track in mx player
His cousin nodded. “So it’s not magic. It’s just knowing where to tap.”
“Arnav, yeh sab English mein hai. Mujhe kuch samajh nahi aayega,” she said, adjusting her spectacles. (I won’t understand a thing.) Amma was already lost in the wormhole scene
“Don’t worry, Amma. I’ll find the Hindi audio,” Arnav assured her, though he wasn’t entirely sure how.
It was a quiet Sunday afternoon in Lucknow, and Arnav’s grandmother, whom everyone called Amma , had finally agreed to watch a movie with him. The catch? The film was Interstellar —a Hollywood sci-fi epic—and Amma only understood Hindi. Now every time she played that file, Hindi
He tapped the file. It played. English audio blared. While the video played, he tapped the screen once. The playback controls appeared. Then he looked for the three vertical dots at the top right corner of the player interface. That was the "Menu" button. He tapped it.
“Arre wah! Yeh toh sahi hai.” But there was a problem—the Hindi audio was out of sync. The actor’s lips moved, but the words came half a second late. Arnav didn’t panic.
He went back to the → Audio → and this time, he used Audio Delay slider. He dragged it to -0.5 seconds . Perfect sync.
