Why Convert AIFF to OPUS?

AIFF (Audio Interchange File Format) is a high-quality, uncompressed audio format typically used by Apple devices. While it offers excellent audio fidelity, it comes with large file sizes.

On the other hand, OPUS is a modern, highly efficient audio format ideal for streaming and mobile usage. It’s supported by major platforms like WhatsApp, Discord, and Mozilla Firefox, making it the best choice for compressed audio without losing quality.

Overview

AIFF is an uncompressed audio file format. It keeps the original file without losing any data. This is the main reason why these files require more storage space. One minute-long audio requires nearly 10MB space. It is widely used by Apple Macintosh/Apple Mac and also musicians use this format for their recordings. Exact copies of music can be formed using this format with the added benefit of sound quality, which is well maintained in these files. Though it follows lossless format(not compressed), yet, there is another variant of it named AIFF-C developed by Apple afterwards and it is the compressed version. The only disadvantage of these files is a large size.

Technical description

Mostly AIFF files have uncompressed Pulse Code Modulation(PCM) data which means at regular intervals the amplitude of the analog signal is reduced from continuous-time signal to a discrete-time signal and every sample is quantized to the closest value. An AFF file has various parts which are known as chunks and each chunk has its own ID which is mostly termed as FourCC. This ID is a sequel of four bytes which distinctly identify data formats. The several chunks found in this format are Common, Sound data, Marker, Instrument, Comment, Name, Author, Copyright, Annotation, Audio recording, MIDI data, Application, and ID3. The first two chunks are essential every time(Common chunk and Sound data Chunk). Lastly, these files have the capability of storing Metadata in five chunks-Name, author, comment, annotation and copyright. Metadata delivers information about the data that is data about data.

Overview

It is a format for audio files which compresses the audios using lossy compression. It neglects the redundant information which can not be processed by the human ear. Internet Engineering Task Force (IETF) has standardized this format. It has superseded the Vorgis and Speex. It offers low latency i.e. there is a less delay in the signal when it enters the system and when it emerges out, this results in real-time interactive communication like video conferencing. Due to its good audio quality, it is widely used by in various listening tests.

Technical description

OPUS has good compatibility with low-end embedded processors as it is less complex. Ranging from 6kbps to 510kbps, it can support both variable and constant bitrate coding. Also, the frame size from 2.5ms to 60ms is supported by this codec. It works smoothly and maintains stability (by avoiding the distortion) while mixing of packets from distinct streams. Speech, Hybrid and pure-CELT are the three different methods used for encoding the audios of varied frequencies. For compressing the Speech up to 8kHz, SILk is used which is an audio compression developed by Skype Limited. The next mode, Hybrid uses CELT to compress the audio files above 8kHz frequency or for wider bandwidth and frame sizes 10ms and 20ms are supported by this mode. CELT(Constrained Energy Lapped Transform) is an open and free audio compression format which is especially used in communication that requires low latency. For general audio, the last mode pure-CELT is used. CELT is used for frame sizes which are less than 10ms.
