Select the bitrate range for the Variable Bitrate (VBR) MP3 file. Note that some legacy audio players may display incorrect audio file duration if VBR mode is used, in this case use CBR mode instead.
Set the constant bitrate for the audio track. Leaving this setting to "Auto" will automatically choose a bitrate to achieve a decent quality based on the source audio.
Set the number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).

m4r

M4R is the designated ringtone format for Apple iPhone devices, introduced alongside the original iPhone in 2007. Technically, an M4R file is an AAC-encoded MPEG-4 audio container identical in structure to M4A — the only meaningful differences are the file extension and a duration constraint of roughly 30-40 seconds enforced by iOS. Apple chose this approach so existing AAC encoder infrastructure could produce ringtones without codec-level modifications, while the distinct extension prevents regular music tracks from appearing in the ringtone picker and vice versa. Creating an M4R involves encoding a short audio clip as AAC, trimming it to the allowed length, and renaming the file. iTunes (or Apple Music on recent macOS) and GarageBand both provide built-in workflows, and third-party tools like Audacity handle it equally well. Once synced or downloaded, the ringtone integrates with iOS settings for calls, alarms, and per-contact alerts. Practical advantages include effortless deployment to any iPhone through iTunes sync or AirDrop, high-quality playback from the AAC codec even at small file sizes, and the ability to assign individual ringtones to specific contacts for instant caller identification.

mp3

MP3 (MPEG-1 Audio Layer III) is one of the most widely used digital audio encoding formats. It uses a form of lossy data compression to significantly reduce file sizes while retaining near-CD-quality sound, typically achieving a 10:1 compression ratio. Developed by the Fraunhofer Society in collaboration with other digital scientists, the format became an international standard in 1993 as part of the MPEG-1 specification. MP3 files can be encoded at various bit rates, commonly ranging from 128 kbps to 320 kbps, allowing users to balance file size and audio fidelity. The format's efficient compression, broad device compatibility, and small file sizes made it the driving force behind the digital music revolution, enabling practical music storage and distribution over the internet. Today, MP3 remains one of the most universally supported audio formats across virtually all media players, operating systems, and portable devices.
