Frequently Asked Questions
Audio files are compressed by reducing the bitrate (the amount of data encoded per second) and optionally downmixing dual stereo channels into a single mono channel.
If your source file is already an aggressively compressed low-bitrate MP3, re-compressing it cannot shrink the file further without corrupting the audio. ihatetools adheres to an honest disclosure standard and tells you if compression is not beneficial.
The 'Voice / Podcast' preset (64 kbps mono) reduces voice recordings by up to 75% while keeping vocal clarity perfectly crisp.
