Settings

Set the overall output MP2 audio bitrate. If set to "Custom", the recommended range is ≥320 kbps with a maximum value of 384 kbps.
Set the number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).
Set the sample rate of the audio. Music with a full spectrum (20 Hz — 20 kHz) requires values not lower than 44.1 kHz to achieve transparency. More info can be found on the wiki.

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.

mp2

MP2 (MPEG-1 Audio Layer II), also known by its original project name MUSICAM, is a perceptual audio codec standardized as part of ISO/IEC 11172-3 in 1993. While its successor MP3 captured the consumer spotlight, MP2 carved out a durable niche in professional broadcasting that it holds to this day. The codec splits audio into 32 sub-bands via a polyphase filter bank, applies a psychoacoustic model to determine masking thresholds, then quantizes and Huffman-codes each sub-band accordingly. Typical broadcast deployments use 192-384 kbps for stereo, yielding transparent quality with lower encoder complexity and better error resilience than Layer III. These properties explain why DVB television, DAB digital radio, and the HDV camcorder standard all mandate or prefer MP2. Encoder latency is shorter too, an important trait for live broadcasting where lip-sync matters. Three advantages keep MP2 relevant decades after standardization: graceful degradation under transmission errors vital for over-the-air signals, minimal encoding delay that suits real-time broadcast chains, and entrenched regulatory acceptance across European and Asian broadcast frameworks.
