Chii chatinenge tichifunga kuti chaive chakakosha, asi chakanga chisina kuwanikwa. AMR chinomanikidza nekuisa zvinyorwa zvacho mumifananidzo, izvo ziso harichazvione - mabhureki anomira pasi pezvombo zvakanyanyisa, mafrequencies panzvimbo dzekunzwa - uye kubvisa zvachose. Pachimiro chehutano bitrate iyo haisi kutaurwa kune vese. Chii chisina kutaurwa chinogona kudzoreredzwa, saka kushandura kune lossless format inochengeta ikozvino mamiriro sezviri nyore kupfuura kudzoreredza zvakanyorwa. AMR i narrowband speech codec ichiita pakati pe4.75 ne12.2 kbps, ichifananidza nevanhu vanotaura, kwete nezvose zvinotaurwa nevanhu.

Nekuti haisisiri yakavakirwa kutakura mimhanzi. AMR i narrowband speech codec yakagadzirwa yemobile networks, yakagadzirirwa kuchengeta mazwi anonzwisisika pa bitrate inofungidzirwa mu kilobits ane dhigirii rimwe chete. Zvese zviri kunze kwesimba remunhu rinenge richiparadzwa panguva yekutora. Kushandura kuita full-range format kunochengeta kurecording kunogona kushandiswa chero kupi, asi hazvigone kuwedzerazve frequencies dzisingazo sampled. AMR inoravira ndangariro: 8 kHz bandwidth yake inoravira zvese zviri pamusoro pefoni frequencies, uye hapana mari yekudzokorora-kunyora zvinozoidzosera.

Voicemail systems, push-to-talk radios, older handset and telephony recording — anywhere audio had to travel over a narrow, expensive channel. That heritage explains both why the files are tiny and why they sound the way they do. Converting makes them play in ordinary software; it does not, and can’t, add fidelity the capture never had. AMR i Adaptive Multi-Rate, 3GPP standardized speech codec yeGSM voice calls uye mobile voice recorders.

Nekuti format haina nzvimbo yekuchengeta mazita aya. AMR yakanyorwa pamusoro pezvombo, pasina nzvimbo yekuti uwane zita, album kana kuti bhokisi rezvinyorwa, saka vatambi vanoramba vachiratidza zita refaira. Kushandura kuita format ine mazita ndechimwe chezvinhu zvinoita kuti library ikwanise kushanyira — mazita anonyorwa panguva yekushandura, kwete panguva yekudzosera, saka funga kuti uchazofanirwa kuisa chero chinhu chisina kuwanikwa musource.
